Customer: “I’ll take a small cappuccino.”

Me: “Sure. Anything else today?”

Customer: “Just a small cappuccino.”

Me: “Okay, I got that. May I have your name, please?”

Customer: “Small cappuccino.”

Me: “No, sir, I need your name for the order so we can call it out when your order’s ready.”

Customer: *tries to save face* “Err… Small Cappuccino. My name is Small Cappuccino!”
