It was a dealer mistake. I have been playing craps long enough that I have seen many mistakes in MY favor. When a game gets hot and heavy the dealers are under a lot of stress managing bets and figuring odds all while 15 people are hollering and talking to them. Like I say I have seen a lot of minor mistakes but compared to the correct actions they make it is a VERY LOW percentage. I truley admire a craps dealer the way they can handle all the chaos and make as few mistakes as thy do. They deal with chaos as bad as a stock trader on the floor of the New York Stock Exchange!
