Conversation in the store the other day

Me: *looking at some display*
Lady: murmur murmur murmur smoke?
Me: Excuse me?
Lady: Sir, do you smoke?
Me: Uh. No.
Lady: I can't find my husband and he locked the car and the cigarettes are in it. We're from Smithville and we're driving to [somewhere I don't remember] and this is the only chance I'll get. (as she walks off I hear) I'm gonna kill him
