This is very North America-centric. Smoking is still rampant in many countries, including parts of Europe. It was actually a bit of a culture shock for me.
Oh yes I'm aware, I have family in Eastern Europe and yeah... it's different. When I went in the 2010s you could still smoke in most restaurants. I actually have a strange place for that kind of environment. It's charming, it's endearing, in a way. But it probably sucks for public health.
