Yeah, smoking was everywhere. I remember flying when you could smoke.
But the main thing is the smell of stale cigarette smoke was just like this undercurrent of any public place you went. Everyone's car. Churches. Everywhere it was that smell.
Also at least where I was in KS, store clerks didn't give a crap. We could buy smokes in middle school if we wanted. Thankfully I never did more than a brief fascination with cloves (and believe me, smoking too many cloves one night because you're upset over a girl will cure you of that).
