    ____________________________________
    Argued March 14, 2016 – Decided April 1, 2016
    Before Judges Sabatino, O'Connor and Suter.
    On appeal from the Superior Court of New
    Jersey,   Law  Division, Monmouth County,
    Docket No. L-2244-12.
    Rui   O.   Santos   argued    the   cause   for
    appellants    (Shebell    &    Shebell,    LLC,
    attorneys;   Thomas   F.   Shebell,   III,   of
    counsel; John H. Sanders, II, of counsel and
    on the briefs).
    Robert A. Ballou, Jr., argued the cause for
    respondent (Garvey Ballou, attorneys; Mr.
    Ballou, of counsel and on the briefs).
    1
    Defendant Costco Wholesale Corp. was improperly pleaded as
    Costco Wholesale Warehouse, individually and doing business as
    Costco of Ocean Township ("Costco").
    The opinion of the court was delivered by
    SABATINO, P.J.A.D.
    In this slip-and-fall case, plaintiff appeals a judgment
    for the defendant wholesale store entered after the trial court
    declined     his    request     to    instruct   the     jury    with     a    mode-of-
    operation liability charge.              For the reasons that follow, we
    vacate the judgment and order a new trial at which the requested
    jury charge shall be given.             As part of that charge, the court
    shall ask the jury to make a predicate factual determination of
    whether the substance on which plaintiff slipped came from a
    food sample offered to customers at a stand within the store.
    I.
    Although some of the pertinent facts are disputed, the case
    is   uncomplicated      and     it    arises     from      a   rather     commonplace
    situation.         At approximately 6:00 p.m. on Friday, October 7,
    2011,   plaintiff2       Richard        Walker      went       shopping       with     an
    acquaintance in a warehouse store in Ocean Township.                          The store
    is   owned    or     operated    by     defendant       Costco    Wholesale       Corp.
    ("Costco").         Plaintiff    and    his    acquaintance       were     purchasing
    items for an upcoming breakfast fundraiser.
    2
    We refer to Richard Walker as "plaintiff" even though the
    complaint names his wife Kathleen as a co-plaintiff on her per
    quod claim.
    2                                    A-2493-14T2
    According to plaintiff's trial testimony, while he was in
    the course of shopping he passed a small table on which a vendor
    was offering what appeared to be free samples of cheesecake.
    The   cheesecake   samples       were   contained      in    small   paper    cups.
    Plaintiff     walked    past   the   display     stand,      apparently    without
    taking   a    sample,    and   proceeded      toward    an    area   looking      for
    packages of bacon.       He was not pushing a shopping cart, which he
    had left with his acquaintance.              He was wearing sneakers at the
    time.
    Plaintiff testified that, as he turned a corner, he slipped
    on a substance on the floor.            Plaintiff initially perceived that
    the   substance    had    "a   white     appearance     like    a    yogurt-based
    product."     As he fell to the floor, plaintiff noticed that the
    side of his jogging pants were "wet" and "smeared" from the
    substance, although he "couldn't tell [the jury] exactly what it
    was."
    Plaintiff did not estimate in feet the distance from the
    spot where he fell to the cheesecake stand.                  He did indicate on
    a   diagram   admitted    into    evidence     that    the   stand   was     in   the
    diagram's upper right area and that his fall occurred in the
    center right area, referred to as the store's "D-19" section.
    As he fell, plaintiff grabbed the handle of a nearby cart.
    He felt his right shoulder pulling out of its socket, which he
    3                                 A-2493-14T2
    attempted to put back into position with his other arm.                                  He was
    later      diagnosed       with     an    anterior     dislocation          of    his     right
    shoulder, which he contended was caused by the fall.
    The person who accompanied plaintiff to the Costco store
    that    day    was     not    with       him   the   moment    when    he        fell.      She
    therefore did not observe the accident.                        Upon discovering that
    plaintiff had fallen, the acquaintance went over to the store's
    food court and requested a bag of ice for plaintiff.                                 The ice
    bag    was    supplied       and     placed     on    his    ailing    shoulder.            The
    acquaintance         did     not    inspect     the    area    of     the    floor        where
    plaintiff fell.            She was not asked during her trial testimony
    whether       she    recalled        seeing     a    table    with    free        cheesecake
    samples.
    Defendant        presented         testimony     from       several        witnesses,
    including       an     "administration          manager"      of     the     store.          He
    testified that he encountered plaintiff at the accident location
    and that plaintiff told him that he fell on a "liquid."                                     The
    manager observed no liquid on the floor while he was helping
    plaintiff.          However, plaintiff's acquaintance testified, without
    objection, that another unidentified employee had stated in her
    presence that he had "cleaned up that area" after plaintiff's
    fall.      See N.J.R.E. 803(b)(4) (delineating the hearsay exception
    for    a     statement       by    an    opposing     party's      agent     or     employee
    4                                    A-2493-14T2
    concerning a matter within the scope of that declarant's agency
    or employment, made during the existence of the relationship).
    The   administration       manager         explained       that      the    company's
    maintenance policies require employees to walk the store on an
    hourly basis and inspect for trash and spills on the floors.
    While performing such hourly safety walks, the employees use a
    maintenance wagon equipped with a broom, mop and cat litter to
    soak up spills.           According to the store's "floor walk sheet" for
    the     day   of    the    accident,      the      last    floor        inspection     before
    plaintiff's fall was completed at 5:52 p.m.                         Several other store
    employees testified for the defense, and none of them observed
    any     spills      or    substances     on     the    floor       in    the   area        where
    plaintiff fell.
    The defense witnesses confirmed that Costco typically has
    vendors       giving      out   free    food       samples    at     various        locations
    throughout         the   store.        According      to   the     store's         "hard   line
    manager,"        the     stands   are     usually         staffed       by   demonstrators
    between the hours of 10:30 or 11:00 a.m. to about 5:00 or 6:00
    p.m.3     The demonstrators are supplied with a mobile "caddy,"
    brooms, dust mops, paper towels, and cleaning supplies.                                    They
    3
    Another defense witness, the assistant general manager,
    testified that the demonstrators would have been "off the floor
    for the most part by 5[:00], 5:30 on that day."
    5                                      A-2493-14T2
    are expected to be responsible for maintaining the areas around
    their displays.
    One defense witness who performs safety walks at the store
    described    the   offering   of   samples   as    a    "common"     practice
    "throughout the store."       He stated that the samples are provided
    in "bite size pieces," and that "most of the time [customers]
    just pop it in their mouth."            He acknowledged that sometimes
    customers,   particularly     children,    may   drop   the   food    on   the
    floor, but that the demonstrators typically "make sure that they
    pick[] up anything that fell."
    Approximately eight to fifteen kinds of free food samples
    are typically given out on the sales floor at this Costco store.
    The assistant general manager acknowledged that Costco generates
    revenues from the sales of products that some customers buy
    after trying the vendors' samples.           He also acknowledged that
    there are no restrictions on customers walking around the store
    with samples they may take from the display stands.
    Plaintiff contended at trial that Costco was negligent in
    allowing a slippery substance to create a dangerous condition on
    the floor, which could cause an injury to the store's business
    invitees.    He argued that the store's maintenance practices were
    inadequate and unreasonable, and that the store had at least
    6                                A-2493-14T2
    constructive notice of the slippery condition that caused him to
    lose his footing.
    As an alternative to this theory of ordinary negligence,
    plaintiff sought to argue to the jury that the store had created
    a hazardous condition by its "mode of operation" in giving out
    free food samples to customers.            Under this alternative theory,
    plaintiff sought to be relieved of his burden of proving actual
    or constructive notice of the presence of the slippery substance
    on which he allegedly fell.       Plaintiff specifically requested in
    this   regard    that   the   court    issue   Model   Civil   Jury     Charge
    5.20F(11)   to   the    jurors.       That   model   instruction    reads     as
    follows, in two alternative versions:4
    11. Notice Not Required             When    Mode   of
    Operation Creates Danger
    A proprietor of business premises has
    the duty to provide a reasonably safe place
    for his/her customers. If you find that the
    premises were in a hazardous condition,
    whether caused by defendant's employees or
    by others, such as customers, and if you
    find that said hazardous condition was
    likely to result from the particular manner
    in which defendant's business was conducted,
    and if you find that defendant failed to
    take reasonable measures to prevent the
    hazardous condition from arising or failed
    to take reasonable measures to discover and
    correct  such   hazardous   condition,  then
    4
    Plaintiff did not specify at the charge conference which
    alternative he wanted the court to charge.     In any event, the
    variations in the wording do not affect our analysis.
    7                              A-2493-14T2
    defendant is liable to plaintiff. In these
    circumstances defendant would be liable even
    if defendant and his/her employees did not
    have actual or constructive knowledge of the
    particular unsafe condition, which cause[d]
    the accident and injury.
    [Alternate Charge]
    A proprietor of business premises has
    the duty to provide a reasonably safe place
    for his/her customers. If you find that a
    hazardous condition was likely to arise from
    the particular manner in which defendant's
    business was conducted and that defendant's
    employees probably were responsible either
    in creating such hazardous condition or
    permitting it to arise or to continue,
    defendant   is   liable  to   plaintiff   if
    defendant failed to exercise reasonable care
    to prevent such hazardous condition from
    arising or failed to exercise reasonable
    care to discover and correct such hazardous
    condition. In these circumstances defendant
    would be liable even if defendant and
    his/her employees did not have actual or
    constructive knowledge of the particular
    unsafe condition, which caused the accident
    and injury.
    [Where Appropriate Add:]
    If you find that defendant did exercise
    reasonable care in . . . light of the risk
    of injury reasonably to be foreseen from the
    particular    manner   in    which  defendant
    conducted his/her business, then defendant
    would not be liable to plaintiff unless you
    find (a) that the hazardous condition was
    actually caused or created by defendant's
    employees or (b) that defendant had actual
    or constructive notice of the hazardous
    condition   for   sufficient   time to   have
    corrected it and failed to do so.
    8                         A-2493-14T2
    [Model Jury Charges (Civil), 5.20F(11),
    "Notice Not Required When Mode of Operation
    Creates Danger" (1970).]
    Defendant     opposed       the    issuance       of   a     mode-of-operation
    charge,     contending    that    the     factual      context      here   does    not
    warrant such a jury instruction.                  Among other things, defendant
    has argued that plaintiff's recollection of slipping on a white
    "yogurt-based"     product       lacks        a    sufficient      nexus    to     the
    cheesecake samples.        Moreover, the defense has contended that
    the activity of providing such samples does not comport with the
    kinds of "self-service" retail activities that have supported a
    mode-of-operation charge under the applicable case law.
    The court ruled at the charge conference that it would not
    issue   a   mode-of-operation          instruction.         The    court   found    it
    significant that plaintiff had testified that he was unsure of
    what he fell on, having only described it as a "white yogurt-
    like substance."5        The court recognized that the store permits
    customers to walk through the sales area with food and drink,
    but recalled no testimony that would "match up" the free items
    provided that day with the substance on the floor that caused
    plaintiff to slip.
    5
    We discern no meaningful difference between the court's use of
    the term "yogurt-like" and plaintiff's phrasing as "yogurt-
    based."
    9                                 A-2493-14T2
    Accordingly, the court instructed the jurors in the ensuing
    charge    on     traditional       principles          of      premises        liability,
    negligence, and causation.             The negligence portion of the charge
    included plaintiff's obligation to prove defendant's actual or
    constructive notice of a dangerous condition.                       See Model Jury
    Charges      (Civil),    5.20F(8),      "Notice       of    Particular         Danger   as
    Condition of Liability" (2014).
    The jury rendered a verdict for defendant, finding on the
    first question listed on the verdict form that plaintiff had
    failed to prove that defendant was negligent on the date of his
    accident.      This form did not include a separate interrogatory
    asking whether plaintiff had proven the subsidiary element of
    actual or constructive notice.             Because of this, we cannot tell
    from   the    verdict     form   whether       the    jurors    voted     in    favor   of
    defendant on the negligence question because of a failure by
    plaintiff to prove the element of notice or because it found
    that Costco's maintenance practices were reasonable, or for both
    reasons or some other reason or reasons.
    Plaintiff moved for a new trial, reiterating his argument –
    this   time    with     briefing   –    that    the    jurors     should       have   been
    afforded a chance to evaluate whether defendant was liable under
    a mode-of-operation theory.              Again, the trial court rejected
    plaintiff's argument, emphasizing its view that plaintiff had
    10                                     A-2493-14T2
    not sufficiently shown the required nexus between his accident
    and Costco's method of doing business in using food vendors to
    distribute free food samples.
    The court faulted plaintiff for being "unable to decisively
    identify the substance that he . . . slipped on[.]"                    The court
    noted that "no other evidence was introduced to show what the
    substance was or where it might [have] come from other than the
    suggestion that there was a cheesecake sample display nearby."
    As   a    matter   of   timing,   the    court         further   alluded   to    its
    recollection of the evidence that "vendors are all required to
    be . . . off the sales floor by 4:30 [p.m.] and this accident
    happened well after 6 o'clock [p.m.]"                   Lastly, the court found
    it significant that "the item that the plaintiff claimed was a
    yogurt-like substance" was alleged to be on the floor "in an
    area where there were completely other items being sold, i.e.
    fish and frozen goods or cold goods," thus reflecting a lack of
    nexus between Costco's business operations and plaintiff's harm.
    II.
    On appeal, plaintiff contends that the trial court erred in
    rejecting      his      request   for        a     mode-of-operation       charge.
    Affording, as we must, all favorable reasonable inferences to
    plaintiff from the factual record, and with the guidance of
    applicable      case    law,   including         the   Supreme   Court's    recent
    11                                 A-2493-14T2
    opinion in Prioleau v. Kentucky Fried Chicken, Inc., 
    223 N.J. 245
    (2015), and other case law, we agree with plaintiff that a
    mode-of-operation charge was called for in this case.                         Such a
    charge is legally warranted here, provided that it include a
    specific instruction to the jurors to determine, as a factual
    predicate, whether the substance on which plaintiff slipped came
    from a free food sample offered to customers by one of the
    demonstrators.

    "It is fundamental that '[a]ppropriate and proper charges
    to   a    jury    are    essential     to   a    fair    trial.'"      Velazquez    v.
    Portadin,

    , 287 (1981)); see also
    Washington v. Perez, 
    219 N.J. 338
    , 350-51 (2014) (noting that
    "[o]ur     law     has    long   recognized       the    critical     importance    of
    accurate and precise instructions to the jury").                      "A charge is a
    road map to guide the jury, and without an appropriate charge a
    jury can take a wrong turn in its deliberations[.]"                           Das v.

    119 N.J. 2
    , 15 (1990)).
    Our task in this appeal is to determine whether the trial
    court erred in declining to charge the jury on mode-of-operation
    principles as plaintiff had requested, and, if so, whether that
    12                               A-2493-14T2
    charging         error       "may       have     affected         the        trial's      result."
    
    Washington, supra
    ,    219      N.J.     at    351.       For        the    reasons      that
    follow, we are persuaded that the charge should have been given
    in   this     case     and     that      its     omission      was      clearly         capable      of
    affecting the verdict on liability.                        R. 2:10-2 (recognizing the
    appellate court's authority to grant a new trial for errors
    "clearly capable" of producing an unjust result).
    In      civil         matters,       the     trial       court         should       give       an
    instruction          that    appropriately            guides   the      jury       on    the    legal
    basis    of      a    plaintiff's         claim       or   a   defendant's              affirmative
    defense, so long as there is a reasonable factual basis in the
    evidence to support that claim or defense.                               See, e.g., Baglini
    v. Lauletta, 
    338 N.J. Super. 282

    In essence, the court's function in deciding whether to
    provide a factually-grounded liability instruction is akin to
    its    role    in   deciding     whether     to   grant     a    motion    for   summary
    judgment or for a directed verdict.                   The requested instruction
    generally should be given, as long as there is a reasonable
    basis     in     the     evidence     to    support       the     predicate      factual
    contention that can trigger the charge, in light of the proofs
    and    all     reasonable      inferences    that     may    be    drawn    from    those
    proofs.       Cf. R. 4:46-2 (delineating the well-established summary
    judgment standard); Brill v. Guardian Life Ins. Co. of Am.,

    judgment).    If reasonable minds might differ on the strength of
    the evidence, the court must "ensure that any legitimate dispute

    B.
    Mode-of-operation          liability      principles       have    long     been
    recognized in our state, in factual contexts where a dangerous
    condition    of    the   premises      has   been   shown      to   arise    from    a
    defendant's       decision   to   provide       goods    to   customers      through
    "self-service"      methods.      As    Chief    Justice      Weintraub     observed
    fifty years ago in Wollerman v. Grand Union Stores, Inc., 
    47 N.J. 426
    , 429 (1966), a case in which a supermarket customer
    shopping in the vegetable section slipped and fell when she
    stepped on a string bean on the floor:
    When greens are sold from open bins on a
    self-service basis, there is a likelihood
    that some will fall or be dropped to the
    floor.   If the [defendant] operator chooses
    to sell in this way, he must do what is
    reasonably necessary to protect the customer
    from the risk of injury that mode of
    operation is likely to generate; and this
    whether the risk arises from the act of his
    employee or of someone else he invites to
    the premises. The operator's vigilance must
    be commensurate with that risk.
    [(Emphasis added).]
    15                                  A-2493-14T2
    As    the    Chief      Justice       further          noted        in    Wollerman,           if     the
    dangerous     condition          on   the    floor       was        the    result         of   another
    patron's     conduct       in    dropping        the     string          bean,       "since     [that]
    patron's carelessness is to be anticipated in this self-service
    operation,       [the]      defendant         [retail          store]          is    liable,        even
    without notice of the bean's presence on the floor[.]"                                              
    Ibid. (emphasis added). The
    effect of a mode-of-operation theory of liability — in
    self-service       situations         where       there       is     a     reasonable          factual
    basis in the evidence to support that theory — is to relieve a
    plaintiff of having to prove the usual element of actual or
    constructive notice of a hazard, which otherwise is necessary
    for an ordinary claim of negligence.                            Such circumstances give
    rise to "a rebuttable inference that the defendant is negligent,
    and   obviates       the    need      for   the        plaintiff          to   prove       actual     or
    constructive notice."             
    Prioleau, supra
    , 223 N.J. at 258.
    The    applicable           Model         Civil     Jury           Charge,         5.20F(11),
    implements       this       concept,        by        instructing          that       a    defendant
    proprietor       that      has   engaged         in    such     a    self-service              mode    of
    operation may be liable for an injury proximately caused by such
    a    dangerous    condition,          "even      if     [the]       defendant         and      his/her
    employees did not have actual or constructive knowledge of the
    particular     unsafe       condition        [that]       cause[d]             the    accident        and
    16                                            A-2493-14T2
    injury."          
    Ibid. However, the model
    charge does not make a
    proprietor        strictly      liable    for     a       slip-and-fall       accident       just
    because the hazard on the floor stemmed from a self-service mode
    of   operation.           The    model    charge          also    makes      clear    that    the
    defendant is not liable in such circumstances unless it "failed
    to   exercise        reasonable      care       to       prevent     such     [a]     hazardous
    condition from arising or failed to exercise reasonable care to
    discover      and    correct       such    [a]       hazardous       condition."           
    Ibid. (emphasis added); see
    also 
    Prioleau, supra
    , 223 N.J. at 259-60
    (noting that the defendant in such cases may rebut the inference
    of   liability       with       counterproof         that    it     exercised        reasonable
    care, in light of its self-service mode of operation under the
    circumstances).
    Our case law has found mode-of-operation liability concepts
    specifically        applicable      to    situations             where   a   proprietor      has
    operated      a    cafeteria      within    a     retail         establishment        in   which
    patrons are permitted to carry food and drink freely within the
    confines of the premises.                  For example, in Bozza v. Vornado,
    Inc., 
    42 N.J. 355
    , 358 (1964), the Supreme Court held mode-of-
    operation         principles      applied   to        a    cafeteria-style           restaurant
    where   the       plaintiff      slipped    on       a    "sticky,       slimy"      substance.
    Patrons of the restaurant would order food at a counter, and
    were then permitted to carry that food to other parts of the
    17                                        A-2493-14T2
    restaurant without trays or lids for their beverages.                           
    Ibid. The activity was
    treated as a "self-service" mode of operation
    despite the fact that patrons were initially served food at the
    counter by the defendant's employees.
    Similarly, in Ryder v. Ocean Cty. Mall, 
    340 N.J. Super. 504
    , 509-10 (App. Div.), certif. denied, 
    170 N.J. 88
    (2001), we
    concluded that the "mode-of-operation" rule applied to a retail
    mall where the plaintiff slipped on an "Orange Julius" drink
    spilled in a common area where shoppers often stopped to consume
    food that had been purchased elsewhere in the building.                      Citing
    Bozza, we ruled that the practice of allowing patrons to carry
    food    and    drink     within   the    confines     of    the   defendant's    mall
    rendered it "the functional equivalent of a cafeteria."                    
    Ibid. In Nisivoccia v.
    Glass Gardens, 
    Inc., supra
    , 175 N.J. at
    565-66,    the     Supreme   Court      found   the     mode-of-operation    theory
    applied where a plaintiff had slipped on loose grapes near the
    checkout lanes of a supermarket.                  Testimony during the trial
    showed that grapes most frequently had spilled onto the floor in
    the produce aisle and the checkout area of the store, after
    being handled by either patrons or employees.                     
    Id. at 562.
        The
    Court     underscored      in     Nisivoccia      the      various   "self-service"
    aspects       of   the   defendant      store's     operations,      including    the
    customer's handling of produce in the aisle, and later placing
    18                                A-2493-14T2
    the items on the checkout counter. 
    Id. at 565.
                    The Court held
    that the "'[m]ode of operation' . . . includes the customer's
    necessary handling of goods when checking out, an employee's
    handling of goods during checkout, and the characteristics of
    the goods themselves and the way in which they are packaged."
    
    Id. at 566.
      Hence,    the     mode-of-operation    concept    applied,
    despite the employees' presence and involvement in the checkout
    process.
    These   cases   and   their    mode-of-operation       principles    were
    recently cited with approval and applied by the Supreme Court in
    
    Prioleau, supra
    .        The factual setting in Prioleau involved a
    plaintiff who slipped and fell on a greasy floor while walking
    to a restroom in a fast-food restaurant.               
    Prioleau, supra
    , 223
    N.J.   at   251.   The   plaintiff     argued   that    the    proprietor    was
    liable based on a mode-of-operation theory, contending that the
    greasy condition of the floor was likely caused by employees who
    tracked grease on their shoes while going to the restroom to and
    from the kitchen.        The Court rejected that theory because the
    alleged condition was not the result of a "self-service" aspect
    of the restaurant's operations.         
    Id. at 264.
    The Supreme Court clarified in Prioleau that the concept of
    "self-service"     signifies    that    "customers     independently    handle
    merchandise without the assistance of employees" at some point,
    19                              A-2493-14T2
    increasing    "the   risk    that   a        dangerous    condition    will    go
    undetected[.]"       
    Id. at 262.
            Moreover,    in    analyzing    the
    underlying facts in Prioleau the Court observed that
    nothing in the record suggests that when she
    fell, plaintiff was engaged in, or in
    contact with, any self-service activity,
    such as filling a beverage cup at a
    restaurant soda machine, selecting items
    from a condiment tray, or that patrons were
    carrying their drinks or food to the
    restroom area.
    [Id. at 251 (emphasis added).]
    In   keeping     with   these   mode-of-operation           precedents,   the
    present case qualifies as a "self-service" context with respect
    to the free cheesecake samples that were offered to customers
    within the Costco store.         Although a defense witness described
    the samples as "bite sized," that same witness acknowledged that
    at times customers, particularly children, would walk away with
    the paper cups containing the samples without consuming them on
    the spot.
    Here, as in Bozza and Ryder, the customers were freely
    permitted by defendant to carry food items around the premises,
    and to consume and discard them at their own pace.                    Given that
    mode of operation, it was surely foreseeable that some portions
    of the cheesecake samples could be dropped on the floor, out of
    the sight of the demonstrator who had been distributing them at
    the sample table.       It was also foreseeable that some patrons
    20                              A-2493-14T2
    might take away an extra sample cup for a companion who was
    shopping with them in another location of the store, and that
    food fragments from those extra samples could be dropped as
    well, away from the vendor stand.
    We recognize that the "self-service" fact patterns in Bozza
    and Ryder involved food and beverage items that were purchased
    by customers on the premises.                   Cf. Troupe v. Burlington Coat
    Factory, 
    443 N.J. Super. 596
    , 604 (App. Div. 2016) (finding a
    mode-of-operation theory inapplicable where a customer slipped
    on   what   appeared     to   be    a     berry   that   was   neither    sold   nor
    provided by the defendant store).                 However, we discern no legal
    significance in whether the edible items are offered within a
    defendant's establishment for free or instead for sale.                     As the
    assistant    general     manager        acknowledged,    the   free   samples    are
    offered to customers for its own business advantage, as a method
    of promotion and advertising to encourage customers to purchase
    take-home versions of those same products.
    To    be   sure,   our       case    law    requires     that   a   plaintiff
    demonstrate a reasonable nexus between the store's self-service
    activity and the dangerous condition allegedly producing his or
    her injury.      See, e.g., 
    Troupe, supra
    , 443 N.J. Super. at 603-04
    (reiterating the nexus requirement); Arroyo v. Durling Realty,
    LLC, 
    433 N.J. Super. 238
    , 245-46 (App. Div. 2013) (rejecting a
    21                              A-2493-14T2
    mode-of-operation claim where no nexus was shown between the
    defendant's sale of telephone calling cards displayed on a rack
    inside     of    the       defendant    store       and    plaintiff's        accident     in
    slipping on a discarded phone card on the sidewalk outside of
    the store).
    Viewing       the    record     here,    as    we    must,   in    a     light    most
    favorable       to   plaintiff,        there    is    a    reasonable     factual       basis
    supporting such a nexus in this case.                        However, the jury must
    first be persuaded that the white substance on the floor that
    plaintiff perceived to be "yogurt-based" was, in fact, a portion
    of the free cheesecake samples.                  If the jury is not convinced of
    that source, then it must render a verdict for defendant on the
    issue.
    We recognize that plaintiff was unable to identify with
    precision the substance on the floor that allegedly caused him
    to slip.        There is a plausible basis, however, to believe that
    the white substance could have been cheesecake, which may well
    have     become       softer,        creamier,       and    more    "yogurt-like"          in
    appearance       after       being     displayed      in     sample      cups    for     some
    unspecified time at room temperature.                       Plaintiff's inability to
    describe the substance in more exact terms is understandable
    given the sudden and traumatic nature of his fall.                              Of course,
    he   may   well      have     been    mistaken       in    his   description       and    the
    22                                  A-2493-14T2
    substance could have come from another source, but that is a
    factual matter for the jury to evaluate.
    We    are   mindful      that,   apart      from    the    admissible            hearsay
    statement that plaintiff's companion claimed to have overheard,
    none of the store employees who testified admitted that they
    observed any foreign substance on the floor in the area where
    plaintiff fell, but that does not render incredible plaintiff's
    claim       that   the    substance     was      there.          Nor        do    the    hourly
    maintenance floor checks conducted by staff logically rule out
    an inference that a cheesecake sample had been dropped onto the
    floor during the interim after the last inspection took place,
    or that it had been overlooked during the inspection.
    We likewise are mindful that the vendors were expected to
    leave the store, as one witness noted, by 6:00 p.m. and that
    plaintiff estimated that the time of his accident was after 6:00
    p.m.     Even so, we disagree with the trial court's post-trial
    observation        that    the     estimated        time     frame           eliminates          a
    reasonable possibility that the offending morsel was dropped on
    the floor at some point before 6:00 p.m. and had not yet been
    detected or swept up when plaintiff stepped on it.                                Furthermore,
    the     diagram     of    the    premises        attested    to        by        plaintiff     is
    reasonably consistent with his claim that the location of his
    23                                          A-2493-14T2
    fall was a relatively short distance from where the cheesecake
    samples had been offered.
    The trial court failed to give plaintiff the benefit of
    these reasonable inferences when it declined to allow the jurors
    as fact-finders to consider whether the factual predicates for
    mode-of-operation          liability          were     proven       here.          Although
    plaintiff    has    not    provided       a    particularly         compelling     factual
    basis to support his mode-of-operation argument, he presented
    enough    evidence    to    at    least       justify       the    model    charge    being
    issued.     The jurors should have been allowed to evaluate whether
    he met his threshold burden of proving the necessary factual
    nexus to a defendant's self-service activity.                        There also remain
    important    factual       questions      about       whether       the    substance     was
    actually    observed      on    the   floor,         whether      Costco's   inspections
    were    adequate,    and       whether    the        locations      and    hours    of   the
    demonstrators'       activities        actually        coincide      with    plaintiff's
    theory of liability.
    C.
    We therefore conclude that the trial court's rejection of
    the    mode-of-operation         charge       here    was   prejudicial       error,     and
    that plaintiff is thereby entitled to a new trial at which the
    charge will be provided.              That said, we provide several caveats
    for guidance to the court and the parties.                         First, as plaintiff
    24                                   A-2493-14T2
    conceded at oral argument on appeal, the question of ordinary
    negligence is not to be tried a second time.                    Plaintiff already
    has had a fair opportunity to convince a jury at the first trial
    of Costco's liability under ordinary negligence principles and
    failed.       That claim is conclusively decided.              See Henebema v. S.
    Jersey Transp. Auth., 
    219 N.J. 481
    , 491-92 (2014) (holding that
    when a new civil trial is ordered because of a defect in the
    jury instructions, the original jury's disposition of certain
    discrete       issues     may     be   preserved        if   those        issues        are
    sufficiently distinct from the other matters that need to be
    litigated in the new trial).
    Second, given the pivotal factual dispute here concerning
    nexus, the trial court on retrial shall include with the model
    charge    a    specific    instruction       advising    the    jurors     that     they
    cannot    hold    Costco     liable    under    a    mode-of-operation           theory
    unless     they   find     that    plaintiff     has     persuaded        them     by     a
    preponderance of the evidence that he slipped on a substance
    that came from the stand with free samples.                    At oral argument on
    the   appeal,     plaintiff       conceded    that   there      is   no    sufficient
    factual nexus to the store's food and beverage concession, which
    was located a further distance within the store from the spot
    where he fell.          His claim at the second trial must specifically
    25                                   A-2493-14T2
    turn on whether or not he slipped on a fragment of cheesecake
    offered at the vendor stand.
    Third, we underscore that defendant retains the ability to
    rebut any mode-of-operation inference with competing proof that
    its maintenance activities to inspect for and clean up debris on
    the store's floor were reasonable under the circumstances.     See
    
    Prioleau, supra
    , 223 N.J. at 259-60; 
    Nisivoccia, supra
    , 175 N.J.
    at 564-65.6
    The judgment for defendant is vacated and the matter is
    remanded for a new trial consistent with this opinion.
    6
    We need not address Costco's provisional argument raised at
    oral argument on the appeal that if a mode-of-operation theory
    is allowed on remand, then Costco should be able to implead the
    demonstrators as third-party defendants.        We refer that
    procedural question, and the appropriateness of such a late
    request to amend the pleadings, to the trial court to consider
    in the first instance.
