I'm with TB on this...
If it were a smoking in pubs/restaurants where freshly prepared food is involved, then fine I wouldn't have an issue with that... Restaurants would be smoke free and pubs could choose between being propper boozers or no smoking gastro pubs (or whatever the term is nowadays).
But no, that would be too easy, so they made it a Health and Safety issue instead. This means that if I were driving my own van every day, I wouldn't be allowed to smoke in it, even if it only had a drivers seat in it. I don't smoke, but resent the fact that I am effectively banned from having free choice 
I think the ban in enclosed places is to protect staff as well.
Well, if you applied to work at a pub/bookies etc, you know what you're letting yourself in for. You worked for British Telecom? If you became a linesman, would you refuse to climb poles on safety grounds?
You're being silly now. Linesmen are employed to climb poles, bar staff are not employed to smoke.
And, before you come back with a smart-arsed answer, I'm going...bye..
