Cherry pits.
No idea whose hands have been in those bags but they grab a handful and snack away on unwashed stolen merchandise. Sanitizer wipe stations but no inclination to take one to put their gd cherry pits in so they can toss them all into one of the trash cans. Instead they put them everywhere else; shopping baskets, display tables, the candy setups at the register...
We're infested (and I don't mean the pits.) I hope each cherry those nasty folks munch on has a family of explosive poo worms happy to have found a home.
