Customer: *to me, serious* “So, are you 50% off too?”

Me: “Excuse me?”

Customer: “Your sign says that everything is 50% off. That includes you, right?”

Me: “Sir, I can assure you that I am not for sale. The sale is only on Christmas items, and I am not included.”

Customer: *still serious* “But you work here! That means you’re for sale too!”
