Keep the change
Selling secondhand books at our church bazaar of America, I got into an argument with a prospective customer. He was interested in buying The Pocket Book of Ogden Nash but claimed it was overpriced at a half dollar. Other paperbacks were selling for five or nine cents each. I pointed out that the book was in good condition and Nash was a fun poet. Therefore the price was reasonable. He said it was a matter of principle and he couldn’t accept it for such a high price. Ultimately, I agreed to sell him the book for nine cents. Triumphant, he paid with a $10 bill。
“Keep the change,” he said generously。
