Around my neck of the woods, the majority of the people who who work in bars are smokers themselves. I started smoking because it helped me not eat when I was bulimic. And just to put out there, I'm the youngest of 4 children, who were raised by two smokers. I'm the only one who picked up the habit. And none of my siblings have any issues from second hand smoke. So I agree that things need to be proven before legislation is enacted.
