(A woman comes in and appears clean and normal. She hands my coworker a plastic bag.)

Customer: “Could you be a dear and throw this away? I hate having trash in my car.”

Coworker: “Sure…”

(As my coworker takes the bag, which isn’t sealed, stuff leaks all over her desk. She leans down to examine it, and it is vomit.)

Customer: “That is disgusting! You spilled my vomit all over your desk. I should have your boss fire you for making me feel sick all over again!” *storms off*
