What if that bar adjoins a restaurant? Would it be okay to allow smoke to drift into the restaurant? I'm thinking a place like TGI Fridays or Applebees.
What of the non-smoking waitress at that bar that can't afford the luxury of simply quiting and taking another job. Shouldn't work conditions be made as healthy as possible for workers? OSHA, after all, has a lot of say in this regard when it comes to unsafe or unhealthy working conditions in other industries.
