Smokers routinely light up at bus stops, elevators, parks, restaurants and even hospitals.

Even in Western countries there’s not much you can do. I keep seeing jerks smoking at bus and metro stops (or right next to/outside those), but what can you do? You won’t call the police for such a small thing, and even if you did for some weird reason, the smoker would be long gone.

Sure, you can ask them to not smoke there. One: good luck with that; two: not like they would stop doing that from then on.

“My mother told me not to meddle in others’ business, even though she has lung cancer,” Ms. Zhang said in an interview.

Yeah, once they smoke under your nose in a place they shouldn’t, they make it your business, as well.
