This is an interesting conversation! I am a non smoker and can not stand the smell--i really makes me physically sick--headaches. Now I know that I am hyper sensitive to smells. Perfume makes me sick too. So with that being said, i think there should be a few rooms that are set aside for smoking rooms. Here is why--a person who smokes goes outside to smoke, then they come back into a nonsmoking room and sit on the couch, bed etc. That smell lingers there. I can smell the slightest bit of it. Now my non smoking room becomes a smoke smelling room for me. I have had to move rooms more that once because of this. So if 18% needs smoking rooms, give them too them. Of course I realize that I am the exception and not the rule, but my opinion nevertheless.
