Customer: “Do you sell MP3s?”

Me: “MP3 players, sir?”

Customer: “No, no, no. I want to buy MP3s.”

Me: “You can buy MP3s from our website’s digital store. It’s really easy. However, we don’t sell MP3s in store, I’m afraid.”

Customer: “So, you don’t sell MP3s in store? Why?”

Me: “You can’t hold an MP3, sir.”
