even if she hadn’t told the cashier the stuff was there, it is part of the primary cashier’s job to check for anything left in or on the cart. If the cashier hadn’t rang it up it was not her fault. I know I do not lift heavy items off my cart anytime I grocery shop, but instead push the cart to where the cashier can hand scan them.
Add to it that the woman was squatted down and laying in wait for Helen, that would have me tearing the roof off the store. How embarrassing to be assaulted in such a manner.
Also, by the rules, at least here in okey, they cannot accuse you of theft/shop lifting until you have left the store. Because until you leave the store, no theft has occurred.
