I do agree with you regarding mixing smokers and non-smokers in a restaurant. The restaurant should maintain separate sections if they want. The difference is that I believe no government official should dictate this. If you don't like smoke and the restaurant has smokers, then don't go there, period. The market will adjust.
If you don't like smoke in meal....then patronize restaurants that don't allow smoking or have separate sections.....
