Customers that take things from one area and then throw them in the freezer aisle because they decided they didn't want them. Like, I'm proud you put it in a refrigerated area, but c'mon man, why did you put that gallon of milk, or that carton of eggs in the freezer? That ruins the product guys, please don't do this. I've once found four rolls of biscuits in the freezer that had already exploded because some customer thought it was a great idea to just throw them in there.
