Shopping For A New Hat
My wife and I were visiting her 95-year-old grandfather when he asked us to take him to buy a new hat. My wife took me aside and said, "I'm worried that he doesn't have enough money, and he'll be very embarrassed."
So, I asked the salesperson to tell my wife's grandfather that whichever hat he chose costs $15. I would pay the difference.
Grandpa picked out a hat and was charged $15. After he left, I paid the other $45 of the price. Later Grandpa said, "What a bargain! The last one I bought there cost me $60."
