Famous Ignoramus

Me: “Hello, sir, how may I help you?”

Customer: “Do you have those books in that series?”

Me: “Which series is that?”

Customer: “You know, the one by that famous author.”

Me: “There are lots of famous authors, sir. Do you know what one of the books was called?”

Customer: “I want the third book in the series by that famous author!”

Me: “I’m sorry, sir, but without more information, I don’t know which book you’re after.”

Customer: “This is ridiculous! How could you not know the ones I’m talking about? They’re FAMOUS!”
