Common in restaurants as well. It's downright bizarre to think about now, but I remember as a child, at family restaurants like Friendly's and Howard Johnson's (which itself is an anachronism), being asked by a cheery-faced hostess whether we wanted "smoking or non-smoking".

It was interesting especially juxtaposed on current reality. I hated smoking (ok I hated 2nd hand smoke as a non-smoker). But somehow, it was the right of the individual to smoke; when, where, and how they pleased. It didn't matter that other people in the space shared the air. Compared to present when the world is looking to bend over backwards to avoid putting smoke in someone else's air on a plethora of different topics. Many, that I've never contemplated. Like, for instance, I never thought I could get yelled at for using what I thought to be the correct pronoun while saying "yes sir, thank you". I'd think they'd just recognize my attempt canned politeness and say "you're welcome" and recognize why people think of them as a "sir" during casual brief interactions (because they were wearing men's clothes & had facial hair).

I assure you non-smokers spent plenty of thought on it.
