Many players who make pass line bets can't afford to take any odds or full odds behind the bet once the number is established. You can place the odds if the person allows you. The casino has no edge on the odds and in the long run your expectation is to break even. That could be a lot of casino fun with no expected cost! One caveat: Make sure the person behind whose bet you're taking odds fully understands what it is you are doing. You don't want to win a bet only to have the man or woman scoop it up and keep it.
