Cordless By Extension

I work at a lighting store.

Customer: “I need cordless extension cords.”

Me: “We don’t sell those.”

Customer: “Oh, do you know who does?”

Me: “No one. They don’t exist.”

Customer: “Yes, they do! My brother told me about them!”

Me: “It’s in the name, sir.”

Customer: “What do you mean?”

Me: “A cord can’t be cordless.”

Customer: “Well… they should be!” *Storms out*
