Why? Just because something is private does not give you the right to do whatever the fuck you wann do with it, since you're operating a business establishment.

An bar/club/establishment is not the same kind of private property as your own house where you can do what you want and let in whoever you want, it's a business that needs to comply with state laws. And state laws say non smokers shouldn't be forced to inhale tobacco smoke in establishments.
