..presumably because they thought that to do so would be profitable.
And the government didn't even have to force them to.
Most restaurants in my area are non-smoking for exactly this reason.
Seems like the best reason to me.
(Ever notice that when a restaurant bans smoking few people complain, but when the people impose their views by trying to get government to ban all smoking in restaurants, it becomes a divisive issue for the community?)
who will re-clarify that banning smoking in public buildings is OK with her, but she thinks restaurant owners should be allowed to make their own decisions.
And who isn't a smoker, FWIW.
