Has anyone ever gone in to Popeyes a few mintues before closing and asked what they do with any leftover food or expired food? Do they throw it away? Has anyone ever been given the food they are about to throw away? Or any employees here ever had a person ask this question? Because when I go in there I see all this chicken, biscuits, beans & rice, mac & cheese, possibly shrimp also, pre-made just sitting on the warmer shelves and I'm thinking what happens at the end of the day if no one orders all that?
