I worked as a grocery store cashier briefly, and I think the single most memorable customer I had was a lady that came in, right at closing time, with two shopping cars, one with dozens of frozen dinners and other stuff I don't remember, and the other containing what I'd guess to be every single bunch of bananas left on display. At the very least, enough to fill the bottom of a shopping cart. They told me the bananas were for some event their church group was doing.
