That's a bunch of c**p and you know it. Smokers sit with like-minded people in bars and restaurants. If someone doesn't like the smell of smoke, they sit in the non-smoking section. Where there are ashtrays there are people who smoke. And if there is no ashtray, I don't lay my money down.
Sorry, this doesn't work. Nearly every restaurant I've ever been to that had smoking and non-smoking sections did an awful job of separating the two. Simply put, when the rights of one group (smokers) and the rights of another group (those who don't) conflict with each other, someone has to win. In this case, the CLEAR majority decided that they no longer wanted to allow smoking in restaurants. It's that simple. Frame it as an employee-health issue if you want, and that's the way the amendment was written, but what it's really all about is - you don't have a right to blow smoke in my face, whether you're sitting next to me or on the other side of the restaurant where it can waft its way over to my table.
