I haven't played roulette and I'm not even sure what the rules are. I wouldn't be game to try it at a casino. It's not that I have any huge moral objection to gambling, I'm just very fond of hanging onto my money.
No, I never have. I only go with 2 friends, to our local casino for the Christmas buffet. We have never played the machines nor anything else while we’re there! Even on the 11 cruise ships, we’ve only used the casino as a shortcut, to the restaurants or our room!
