I'm old enough to remember when smoking was banned in bars/clubs in the UK. It went from a musky smell to body odour, and it took practically all venues by surprise.
Now, I'm so glad that indoors smoking was banned. Looking back, it was fucking gross, and while sadly lots of people now vape indoors it was a huge improvement to basically be able to actually breathe in those places.
I came to Ireland when they just banned smoking and it was still legal in Germany. The first time I walked into a pub and ran against a solid wall of sweat and beer farts I missed smoking.
Seriously this! I grew up poor so going to restaurants was a 2-3 times a year thing. And as a kid, going to one meant non-smoking area, where the nasty ass smoke would still waffle over. And my eyes would get irritated, id get really sick and cough nonstop for days.
It didn't even notice the coincidence until it happened to me at a friend's house in college who was also a heavy smoker.
