You should be able to go out to eat in a restaurant without sitting next to smokers. I do not enjoy that, but seriously can't remember a place where you can sit down for a meal that there isn't a non-smoking section. To make a “bar” non-smoking though? Cripes, that's like banning pitchers of beer in a bowling alley, or better yet their indoor burger grills and grease fryers which give them their unique awful stench which greets you at the door, sticks to your clothes, and makes them spraying the rental shoes laughable.
The worst thing is states that actually close bars with a “bartime” law. That’s just insane.
