Which is by far one of the best bets in the casino. Your come betting strategy has something like a 1.41% house advantage. I’ve witnessed many many many people at the craps table who sound like they know the game inside and out and would intimidate the hell out of a newcomer only to just blow through racks on garbage props/bonus/hardways yada yada yada. For hard four and hard ten, it's a distressing 11.1. The house edge is a painful 9.1 for hard six and hard eight. The pass bets house edge is just 1.41, while the dont come bet offers an even lower house edge of 1.36. Anyone can make the bet or take it back anytime (before resolution). The main bets in the game of craps are: pass bet come bet don’t pass don’t come These bets have the lowest house edge of them all, so you should be picking in for the most part when playing.
It’s a semi-low volatility strategy that will keep you at the table longer albeit less chance of being a big winner compared to the odds bet. The centre of the table is where these bets are placed. Playing like this is so far from the worst you can do at the table. So OP, the dealer is correct in showing you the odds bet, but ultimately it’s totally up to you. In fact, come/line bets are the cheapest second to odds. There are far worse bets to make at the table via props/bonus bets, than a few come bets.
I personally wouldn’t play like OP, but only because I have my own preferences and strategy. Place bets are like 200-300% more expensive house advantage than a come bet.
