High, How Are You?

(A customer comes up to my till, and I greet him like I normally would.)

Me: “Hi, how are you today?”

Customer: “I’m high. How are you?”

(I burst out laughing.)

Customer: *smiling* “Betcha weren’t expecting that.”

Me: “Nope, I definitely wasn’t. I’m doing well, sir. Not as well as you, though.”
