I had a newbie ask what to do with some trash he found either in a cart, or on the salesfloor. They were two, empty, ice cream cups. He asked me what to do with them, expect he said it like this, "Uh, so like, what do I do with this kind of stuff." I told him, "It's garbage, just throw it away." He proceeded to just leave it on my counter at guest service, despite the massive trashcan I have, with some other garbage, after leaving his stray cart filled with tags and fixtures I'm assuming he also didn't know what to do with and was too lazy to find out.
I hate that, "someone else will do it" mentality. It's completely mindless.
