When i moved to herts some years ago, i became a bus driver and on my travels i found a pub that had a very successful gimmick, the sign outside said.........
We're smoke-free
this was four years before the smoking ban came in place, but they were always really busy everytime i went past.That's great right? Well when the smoking ban came in place they had to find a new gimmick as people could then go anywhere for a smoke free drink, also had to spend a fortune rebranding and removing their nolonger valid gimmick from their leaflets,sign, ads etc

yet another business affected by the smoking ban
