I was hosed out of the ace pool once when nobody won it and there was a giant throw off for it...The TD announced that it would take place immediately...and GO! It had been a good 30 minutes since there had been any sort of activity; everybody was waiting around, and I had put my Discs back in the car. I managed to sprint for them (along with ten other people), returned, and tossed my Disc about 3 seconds after everybody did. "Nope, too late!"
I was the closest to the pin. It was for over $100. Haven't played in a tournament since.
