I've been playing craps for years now but only on my last trip did I start dipping into come bets. So 2 questions: 1. Can you set down a bet (say $5) and tell the dealers "make that a come bet on the 9"? Or does it have to be rolled on the 9 for it to be put there first? 2. Can you at any point in time say "turn off my bets" including come bets? (I know place bets can be turned off but I'm unsure about come bets).
