For me it would depend on the book. If it's Bowmans, Bodog, SIA, Sportsbetting.com, or sportsbook.com I would keep the money in a flash. If it's Canbet, Rio/Skybook/IIS, Hollywood, or 5Dimes, I would give it back without thinking. Pinnacle and BetWWTS I would have to think about it because on one hand they are fair but on the other hand they have so much $$$ that they wouldn't even notice it.
