I never heard anything otherwise, although, it is said to be tradition that most guys that come with W's out of these situations tend to cut big amounts out of bets to help out. Kinda keeps it friendly. Personally, I ran a bike a while back for 2k and he laid it down. I cut him 50% out of pity, and we went our ways. My opinion: I'm still leaving with a grand, might as well be nice about it.
