(It’s late at night and a solitary customer pulls up outside and fills her car at the pump. She calmly opens the station’s door and comes inside to pay at the booth, but realizes she left her wallet in the car.)

Customer: “OH MY GOD! LET ME OUT! LET ME OUT! MY WALLET IS IN THE CAR, UNLOCK THIS DOOR!”

Me: “It is unlocked.”

Customer: “But it says you’re closed!”

Me: “What does the other side of the sign say?”

Customer: *looks at me like I’m stupid* “Open, but it says you’re closed!”

Me: “Why does it say ‘Open’ on the other side of the sign?”

Customer: “Look, you…” pauses, then blushes bright red* “… oh.”

Me: “You need some chocolate.”

Customer: *smiles* “Yes, I do.”
