He whispers to the usher, "This is a mystery, and I have to watch a mystery close up. Get me a better seat, and I'll give you a handsome tip."
The usher moves him into the second row, and the man hands the usher a quarter.
The usher looks at the quarter, leans over and whispers, "The wife did it."
Moral of the story. True sales professionals know to always follow through on gratuities. Why would you ever mess with someone who handles your food, or could get you better seating in the future?
"Promises are like babies crying in a theater, they should be carried out at once."
