FWIW I worked in a supermarket. Go nuts, nobody cares. My asshole manager would make me keep moving everything anyways, and I later learned this was to prevent customers from easily finding the things they wanted.

Wasting company time hurt the company, not me. I didn’t mind collecting shopping carts either. My friends weren’t waiting for me to get off work because the shifts were irregular anyways.

I didn’t even care about stuff that risked the store shutting down, because nobody intends to work at a grocery store for very long. Nothing hurt my pay because it was already minimum wage. Go ahead and steal, I sure wasn’t paid to care.
