Snowguy, your idea is fine, but I doubt many restaurants will jump through those hoops to allow smoking, which is fine with me, but I'm just saying.
I remember when I was young and my parents would take me to a restaurant with smoking. The other non-smoking area always had a hint of tobacco smell to it, and that always turned me off. I suppose that explains much of why I oppose allowing smoking in restaurants and other public places. Sure, it's a choice of sorts, but if you choose to smoke, you are bothering more people than just yourself. This is coming from a guy who's usually all about personal freedoms, as long as you are not harming anyone else.
My county passed a no-smoking ordinance in like 2004 and allowed smoking in bars from 8pm-3am until 2007 when they could only allow smoking in separately ventilated smoking rooms. Almost every bar built one... only for it to be a waste of money when the state banned smoking in bars/restaurants outright in 2008.
