A different time. I remember the first question from the host at a restaurant being "smoking or non?"
One of my favorite bars in college allowed smoking upstairs (and still does, although how many college kids actually smoke?). I really do miss having a cigarette in one hand and a frosty beer in the other.
In San Francisco, you can still find buildings where the elevators have ashtrays, though usually the actual tray is gone.
Apparently the thought is: better a smoking cheater stubbing it out in the loo ashtray than hiding a burning ember in the seat backs.
