I know I smelled. When I use to go out for a smoke break whoever was in the elevator would make a comment. I actually don't mind the smell when someone is smoking cigs and love the smell of cigars. The last thing I want to turn into is one of those ppl who make faces and wave their hands.
I can tell if a smoker has been in the elevator in the last half-hour now. I'll never say a thing, though, because I was one of them for 40+ years. It was quite a revelation.
