A Double Dose Of TMI

(I am paying for my items when this exchange occurs:)

Me: *to the cashier* “Hello, how are you today?”

Cashier: “I‘m a bit tired. I‘m working a double-shift today.”

Me: “Oh, well, you should treat yourself to a coffee. It might wake you up a bit.”

Cashier: “No, coffee makes me poop.”

Me: “Oh… well, I guess you could get a tea?”
