UK??
As guest above says, we've had the ban in Scotland for over a year now, and it's also already in force in Wales, and bl##dy great it is too!
No more having to wash your hair and put all your clothes in the washing machine after a night out.
The only down-side I can see (and I wouldn't turn the clock or the law back) is that on a nice afternoon, the pub gardens will be full of smokers.
Some pubs have seen their takings go UP (contrary to the doom and gloom predictions of the licensees and anti-ban brigade), as the non-smokers now find it possible to go to a pub in comfort.
