Relative availability of evidence to the parties is a circumstance to be considered in determining what should be required for making a submissible case. In Moss, plaintiff slipped and fell on a green liquid on the store's parking lot. In contrast to Sheil, the accident did not occur inside a self-service store, but rather in a parking lot owned by the store and there was no showing that the slippery substance which caused the fall was a type of merchandise handled by the store. However, the court held that the parking lot was an integral part of the store, maintained to attract customers, and the duties of the storeowner with regard to the parking lot are essentially the same as those that relate to the inside of the store. Head v. National Super Mkts.
Foreseeable risks extend beyond a given store's products.
Thus, for example, if a store provides plastic bags for its customers' use, it is foreseeable that customers may drop those bags on the store's parking lot. Forrest v. Schnucks Mkts. The store has a duty to protect its customers from dangers created by the bags. Id. Defendant's liability is predicated on the foreseeability of the risk and the reasonableness of the care taken, which is a question of fact to be determined by the totality of the circumstances, including the nature of the restaurant's business and the method of its operation. In this case the accident took place in the restaurant's restroom which is provided for the use of employees and customers.
