I was talking to a smoker friend last night who was very pro-smoking ban (much more so than I was). He said that they were considering amending the Washington ban so that if a bar or club has a patio (and most do these days) you can have a smoke out there. As it stands now, you can't smoke in any area that is under the supervision of an employee, which I think is dumb. I was all for the ban on indoor smoking, but I don't think street or patio smoking is bad.
The main reason I was against indoor smoking, btw, was the situations we would get into in the club that I worked at (the "leather" bar) People would regularly throw their cigs in the trash cans, and they would occassionaly catch fire. Since the clubs are not required to have sprinkler systems (but they will, starting in '08 or sometime around there) I was always afraid of what could happen - all it would take is for someone to scream "fire" and all hell would break loose.
That, and I was tired of getting accidentally burned by drunks with cigarettes, although that usually meant at least an extra five bucks in the tip jar ;-)
