I remember it as that bad. I worked in a small office where everyone but me smoked, and chain smoked. (Well, actually, there was another non-smoker, but when she complained she was let go.)
When restaurants grudgingly started having non-smoking areas (as opposed to no smoking, which was later), I remember one where the non-smoking section was on a raised platform in the center of the restaurant, so instead of getting some smoke, we got all the smoke.
Another time (and this was in 2000, in Kentucky), I couldn't figure out why I was smelling smoke at an airport when the smoking area was glass enclosed. I looked closer, and the glass "walls" were not floor to ceiling, but left about two feet open at the top and the bottom.
