A friend asked someone at a high end swap meet how much a painting was.

The answer was a flip $12.50. So she wrote out the check for $12.50 and gave it to the man and walked off with the painting.

He must have had a heart attack later in the day when he REALLY looked at her check. Her phone number was on the check and he called her and said that there had been a terrible mistake. The cost of the painting was really
$1,250.00.

She was honest enough to return the painting to him. Betcha he never made that mistake again and always is clear on the true cost.
