What is this "choice" thing all about? Because it's your choice to smoke, why do I have to move to get away from you? You're the one with the bad habit.
Non-smoking casinos can work out just fine -- look at Canada. The air is clean in their casinos and the money (after the first few months) is just the same. Smokers can learn to control their craving for a while. Yeah, I'll watch your machine while you go out for a smoke. It's not that big a deal. Get over your selfish cravings, and let the rest of us breathe.

Oh, yeah, like those non-smoking areas really work. I come to Vegas from the Detroit area at least twice a year (this year 4 times) and would love a total non-smoking atmosphere.
There is a non-smoking area in one of the Detroit casinos but they haven't put one new machine in it since it was built. Plus, smoke floats over to it from the predominantly smoking floor. I don't go there anymore.
Across the river in Canada there is a totally non-smoking casino, very nice, very upscale and I'm there at least once a week. It has several "smoking rooms" where ppl can go for a puff. IT's a pleasure to sit down at a slot and not have to look around for smokers or have to get up when someone sits down next to me and lights up. It's a little inconvenient to have to cross over to Canada to play, but you can get used to anything.
Yes, you can get used to anything, including not smoking until you get yourself to a smoking area. The dealers like it, too.
