Not so sure about the use of the word choices Keith - banning smoking is about giving non smokers what they wanted. Choice is either for everyone or it isn't choice - it's dictat.
Choice would have allowed for smoking clubs/pubs/restaurants and non-smoking clubs/pubs/restaurants.
On a more cheery note: A friend's (20 year old non-smoking) daughter says she preffered it in night clubs when they smelled of smoke - now she reckons they just smell of stale sweat and f*rt.
