you are only thinking about patrons. also think about employees, which is what the bill is aimed at. If you are part of a wait staff in a restaurant you are subject to cigarette smoke.
Then you are going to say “well faggy ass hats should go work for a restaurant that doesn’t allow smoking”. To which I’ll reply, “there are only so many jobs in that industry in pittsburgh that fit the bill”. Sure they could move to California, or New york, or Minneapolis, or Denver, or Boulder, or Charelston, or… but it’s a wait job, you aren’t going to move for that and I would bet that a large portion of the staff is here as students just looking for extra money.
The government regulated the coal industry. While black lung may kill you sooner than cigarette smoke, the long term effects of smoking or being in a smoke filled environment are just as tragic.
