(A man comes to my register with a mint chocolate candy bar.)

Me: “Anything else?”

Customer: “Can you break a $100 bill?”

Me: “Actually, I can’t. We just opened and I haven’t gone to the bank today.”

Customer: “Oh, no! Do you know anywhere I can get change? I need this candy right away!”

(At this point I notice his panicked look. Coupled with the fact that he’s buying the most unappetizing candy in the store, I jump to a conclusion.)

Me: “Sir, these aren’t for you, are they?”

Customer: “No.”

Me: “Did your pregnant wife send you out at 8 in the morning to buy this candy?”

Customer: “Yes.”

Me: “For the love of God, man! Get these home to her before you’re in even more trouble! You can come back and pay me later!”

(The customer bolts out the door. He later came back, visibly calmer, and paid.)
