Oh so very this! Work at a university, walking into work in the morning is often in a crowd (a whole challenge to stay upright in itself) and if some git is smoking in that crowd and I can't see them I can't breathe and am clogging up but CAN'T escape... I have long term ENT issues which Do Not Need Triggering kthx. I'd happily make all of campus bar some smoking huts non smoking! I wish the whole world was "smoking only in the designated smoker pits"...

And grr yes to the non enforcement of smoking near buildings, drives me potty that no one cares...

I would be less harmed by someone slapping me in the face...
