At craps, the odds bet you've added to your come bet (a wise move) does not work on the come-out roll. That's because players hate to lose their entire bet when a winning 7 is rolled. Remember, the dice don't know you have a bet working, so they just follow the laws of probability. You should tell the dealer: "Odds work on the come out," and he/se will place a "ON" button on your specific bets. That way if the shooter throws a point number, you'll be paid even money for your come bet and will true odds on your odds bet.
