Spells Something Else Entirely

(I’m the customer in this story. I’ve just seen my doctor for the first time, and she’s sent down a prescription for me to the pharmacy downstairs. I make it up to the window, and there are a ton of people down there, so it’s a little noisy.)

Clerk: “It looks like your prescription isn’t ready yet, but I’m going to write down your name so we can call you when it’s ready. Can you give me your name?”

Me: *gives name*

Clerk: “And who’s your doctor?”

Me: “Dr. Fu.”

Clerk: “Sorry, it’s a little loud, I didn’t quite hear that. Can you spell your doctor’s name for me?”

Me: “Sure. It’s F-U.” *pause* “Oh, my God, that’s not what I meant!”

Clerk: *laughs*
