Here's my opinion as a non-cigarette smoker and someone who wouldn't date a smoker.
I do smoke cigars (maybe one a week). I hate the smell of cigarette smoke on my clothes but it's my choice whether to go into that establishment.

When a person, isn't able to go into a bar (and that bar isn't legally allowed to operated their business how they wish) and have a cigarette then there is something very wrong with our freedoms. Health issues? Certainly, so raise the tax on them to a realistic level and put the money back into healthcase. Ban high fructose corn syrup because that shit, is certainly killing more than smoking and in a country where legal gun ownership is a "right" then get the fuck over it.
Where does it stop?

How's this for a compromise.
Smoking shouldn't be allowed in food service places. Bars can choose whether to allow smoking. Should they allow it, then their front door has to be a massive red or bright yellow with a large "WARNING SMOKING" on the door with a legal disclaimer. Staff working there have to sign disclaimers. There has to be EXCELLENT air systems and filtration in the place ...
... and then they're left the fuck alone.

I bet most of the whiners about this wouldn't think twice about biting into a big mac and a large coke.
