Employees not knowing where things are is a post all in itself! I learned that many items can be cross-categorized, like Manwich can be with the canned chili, tomato sauce, or spaghetti sauce areas. So when I'm stuck I'll think about how something can be sorted and check there before asking for help.
Your description of the checkout brought back so many memories and made me groan out loud :)
Thanks for reading :)
