I would agree with this but you're wrong. It was nearly impossible to find a decent bar/restaurant that did not allow smoking.
Business is all about getting money, making your place of business non smoking is cutting out a HUGE part of the market. You would lose far more money that way than the money you'd lose from people who don't want to smell smoke, especially when 90% of the competition allows smoking as well. It would have just been horrible practice for the places that opted to do it, which is why almost no place did.
If it was just about the "smell" I would almost agree with you, but there are health concerns regarding second hand smoke, so It's a ban I agree with, and I don't see why it's taking away a "personal freedom". There are several other smoking bans that I disagree with however, and I think the "oh my GOSH SECOND HAND SMOKE" crowd is pretty much awful and need to get over themselves.
