Why "way to go Westin"?

What should you or I care if somebody wants to smoke in a room designated as a smoking room?

I don't understand what Westin gains from this. Having a smoking floor certainly can't bother us non-smokers because we won't be on that floor. Why not allow people who smoke (about 20-25% of the population) to have floor and a room where they can smoke. It's OK to not allow it in the lobby or restaurants, but the entire hotel? jeeze

I don't understand why it seems like smokers have become lepers in the US. Strange and unfair.
