I agree with Martin, in a way. I had to do a debate in Government class last semester being AGAINST the ban (even though I am for it..it just seemed easier to be against). Anyways.. I do think it should be the restaurant/bar owners choice to allow smoking. But, if that were the case, why have the law? If bar owners/restaurant owners wanted to ban smoking, they would have done it a long time ago.
But, I do love not having to go into a restaurant, and have them ask "smoking or non?" Even if you are in a non smoking part of a restaurant, you are still able to smell the smoke.
