I Want A Hot Chocolate, But Confused

Me: “Hey! How are you today?”

Customer: “Great! Hey, do you have hot chocolate, but like… over ice?”

Me: “We can do a chocolate milk for you, absolutely!”

Customer: “No. Hot chocolate, but over ice.”

Me: *sigh* “Yeah, we can do that for you.”

Customer: “Awesome!”

Me: “What size would you like?”

Customer: “Uh, medium.”

Me: “Okay! Anything else for you today?”

Customer: “Nope! That’ll do it!”

(I hand him his drink in a cup we typically serve hot drinks in; we make an exception for cold milk.)

Customer: *drink is already in his hand, so he’s felt the temperature, which is very well cold* “Oh, sorry, but I wanted this iced.”
