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. "I'm worried that he doesn't have enough money,
and he'll be very embarrassed," she said.

So I asked the salesperson to tell my wife's grandfather
that whichever hat he chose cost $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.
