Here, after giving general negligence instructions, the trial court instructed the jury with BAJI No. 8.23. That instruction states, in relevant part:“The proprietor of a business establishment owes a duty of care to customers when they come upon the business premises at the proprietor’s express or implied invitation. [¶] ...This duty of care requires the proprietor to exercise reasonable care to discover whether accidental, negligent or intentionally harmful acts of third persons are occurring or are likely to occur on the business premises. If a proprietor knows, or should know that these types of acts are occurring or are likely to occur, the proprietor has the further duty to either give the customer a warning adequate to enable the visitor to avoid the harm, or otherwise to protect the visitor against the harm. [¶] ...A failure by the proprietor to perform this duty of care is negligence.Thus, the jury was not told that liability in this slip-and-fall situation required that the store owner have actual or constructive knowledge of the dangerous condition that caused the accident. As discussed above, a plaintiff must show that the owner had notice of the defect in sufficient time to correct it. Wal–Mart’s request for such an instruction was refused.1
