My foot hurts

(Customer removes the lid off of a box of a Bushel of oysters, leaving an open box on the display. She uses the lid to prop her leg up on the motorized cart she’s using)

Me: Ma’am, I can’t let you do that. I can’t have the oysters open in the aisle, plus the barcode is on the top of the box.

Customer: My foot hurts!

Me: I can get you another empty box, it’s a health code violation to leave these open.

Customer: My foot hurts!
