I think non-smokers are more relaxed about smokers than ex-smokers. Once they get a whiff ...
Then again, I always wonder why smokers think it's okay to enter rooms with a smoke.
Or the tram operator who's too cold to step outside while in the waiting area, standing on the steps of his tram and smoking, all the smoke flowing INSIDE the compartment ...
My son's in the hospital at the moment, I stay with him during the night and most of the day. There's another parent tending to her kid, and I noticed that one certain area of the hospital wing had an extreme "ck one" reek to it. Turns out she's a smoker, goes outside to get her fix, then she sprays herself with unisex cologne to try and mask the smell. Now her child will smell cigarette smoke AND become nauseous from the perfume
It's on your skin, your breath, your clothes, it stains your fingers ...
