BTW the smoking area in my watering hole has an air filter and is in a seperate area to the main room(seperated by two doors and corridor of about twenty feet)

You would be quite happy in the main room - its completely smoke free.

You only have to wait until July and you will be able to go to any pub without any nasty side effects.

I'm not a selfish smoker and I don't think I've proved any point at all
