It's the whole point behind outlawing smoking in NYC bars and restaurants.
Working for 8 hours a day in a smokey bar is the equal to smoking 1/2 a pack a
day. Some sort of scientific study. I can agree though, the smoke on my
clothing after being in a club is so thick I can wring it out. I can imagine
what is in my lungs.
I'm glad I work in a non-smoking country club. ;)
