Me: “I have a tall mocha.”

Customer: “That’s me, thanks.”

Me: “Thanks! Have a good one!”

(She returns in less than a minute with a disgusted look on her face.)

Customer: “What is this?!”

Me: “That’d be a mocha latte.”

Customer: “Does it have espresso in it?”

Me: “Yes. ”

Customer: “Ugh, this is the worst thing I have EVER put in my mouth!”

Me, without a beat: “Ma’am, I highly doubt that.”
