And that's a valid point. If I am there first, then I do think the new person has a responsibility to check out the scene before sitting down.Mr. Ninja, while I do understand and appreciate your stand on it, things aren't always going to go the way you like. Are you going to keep moving to a different section of the bar because someone new walked into your area and doesn't like cigar smoke?
What about going to a cigar friendly restaurant then, after dinner, while enjoying your cigar and maybe a libation, a couple comes in, smoking cigarettes and tells you that your cigar is offensive. Are you going to move to a different table? While I agree there are times a softer approach is better, there are times that standing your ground, not allowing YOUR rights to be trampled, is the best, and correct way to handle it.
My apologies for my rant.
A few years ago I was in Vegas at a smaller casino playing blackjack. It was a $2 table (yes, years ago) and it's possible that I had had a few drinks... So I am playing in a manner that most books would suggest not playing like (splitting 10s is always fun). Anyway, a woman came up to the table and sat down immediately to my right and started getting upset with the way I was playing. C'mon, it's a $2 table, I've been playing like that for about half an hour and if she was that concerned about style of play then she should have, at the very least, stood and watched how I played before sitting down. AND probably shouldn't have sat to my right.
Same thing with cigars - if I am the one just sitting down, I'll pay attention to that. But if I am there already, I do expect the new arrival to take some responsibility for where they choose to sit.
