And there was a 'stink' about it (sorry, couldn't resist) when it went into effect. One of the most vocal opponents I personally talked to was a waitress who didn't smoke at a restaurant that served minors.
It's a reasonable law, that respects smokers, non-smokers, and those without a choice. Just like I'm sure there would be a 'stink' if my suggestion of higher cost licensing for smoking clubs went into place.
It's the flat-out bans that get my goat, so to speak.
