We just sat in the non-smoking section.

Cigarette smoke is very clever and is sure to respect a small piece of red rope strung across the restaurant.

And the real answer is we were all just used to the smell of cigarettes. Going for a meal or going to see grandad? Put on some old clothes that can be put in the washing when you come home because they’ll stink. It never seemed to occur to anyone that they could just stop letting people smoke indoors.
