This is a really old story (almost 5 years), but this jogged my memory. One of my first cashier shifts ever, a guest handed me a folded up piece of paper. Thinking it was trash - because I am a human-shaped trash can, apparently - I just tossed it. The guest looked really confused and kept sputtering and making fish faces at me. I asked if there was anything else and the guest finally said no and left. When he made it to the door, two cops grabbed him, and escorted him out of the building. One of the cops came in and both he and the AP walked to my register...laughing their butts off. Turns out, I threw away a demand for cash and to keep quiet about it "or somebody gets it." Sometimes, ignorance is bliss...
