Keep the Change

I was selling secondhand books at the flea market. I got into an argument with a customer. He wanted to buy The Pocket Book of Harry Potter. But he said it was too expensive at 35 cents. Other paperbacks were selling for 10 or 15 cents each.

I pointed out that the book was selling good. HarryPotter was a good book and it wasn’t expensive at all. He said it was a matter of principle. Finally, I agreed to sell him the book for 15 cents. Triumphant, he paid with a $10 bill. "Keep the change," he said.
