If it were me, and I just won 7.5 mil, when they ask me how much tip I want to leave, I ask how much the guy left last year, when they tell me, I double it. I'm a showboat that way. Besides, even after taxes take 40-45% (guess) and your left with your 4million or so, what's $100,000?My guess is that he had a beef with someone associated with the tournament. I mean, come on! $100 tip is like leaving a .10 tip for a $200 dinner, it had to be a statement...or a rumor.
