I had a guest ask to buy a display for a small electronic item once (toaster or coffee pot? Don’t recall which) and when I said we can’t sell the display because the cord has been cut off she just stared at me. After a few seconds she asked “so you won’t sell it?”. I looked her in the eye and said “it doesn’t have a plug. How will you plug it in to get it to work?”
I guess she didn’t realize the plug was attached to the end of the cord.
Edited to add: I guess in this case I was the condescending one! LOL
