About the only gesture I'd have for a $1,000 sundae involves dropping my trousers briefly to half mast and bending at the waist.
Well, look at it this way -- you're a young hedge fund guy with 5 mil in the bank and dating a b-actress to impress your friends. You've already put down the money for the $100,000 summer rental out in the Hamptons and bought all the toys you want. You take Ms. B-actress out to a nice dinner and on the way home say, "let's stop in here" and the fancy ass dessert is waiting for her. It's a gesture.
