You wouldn't let them pump other gases into the air in a restaurant where food is present. There are very few restaurants that have a wall dividing the areas. Smoke still lingers to the non-smoking side and ruins people's appetite. They've already banned it at restraunts, bars, etc. out here in California. It works well with minimal complaints.
People conform to the smoking laws laid out by California law.
There's a time and place for everything. As a former smoker I have never liked smoking at a resturant. It really is a nasty thing and if your out to eat you should not have to deal with it. Austin has-Corpus needs to keep in step with the rest of the world. Dining out should be a pleasurable experience unclouded by smoke.
