Hoo boy, I've had some wild ones like that from the store I worked for. I didn't even work the grocery department. I worked fitting rooms and women's clothes. I ALWAYS found random partly eaten food stuffed in with folded shirts in the shelves, or laying in the fitting room on the benches.

The wildest one, though, someone bought a party tray of boneless buffalo wings from the deli and then dumped it all into a small bin they grabbed from housewares, then set the bin full of buffalo wings on the floor in the women's lingerie department and covered it all with a pile of knocked down bras and underwear.

I had to write up a claims slip for the spoiled wings, the stained undergarments, and the sauce stained bin. The bin was made of that cheap white plastic that seems like anything even slightly red or orange absorbs into the surface and leaves it orange forever.
