You don't "really" think that those non smoking areas keeps the smoke out of the non smoking ones do you? If so....then your smoking has affected your brain. I can even smell the smoke when someone is lighting up outside, in what is supposed to be fresh air. Instant headache right between the eyes! Even if a smoking person goes outside or wherever, when they return, us non smoking people can smell the disgust of them when they return. It hangs in their hair, their body, and their clothes, not to mention how bad their breath smells. It definitely is a catch 22 situation, where no one wins and everyone loses.
