In Ireland, were we have had the ban for several years, it's worked like a charm, especially in the music pubs.
Musicians have welcomed it, particularly the flute and whistle players, who now can get get decent lungs-full of air without inhaling the fouled-up atmosphere; non-smokers are delighted not to end up with sore eyes and throats and not smelling like old ashtrays from somebody else's dirty habits; and by and large, the smokers have accepted it (grudgingly at first), but now seem to regard it as a done deal.
Just after it was introduced a crowd of locals took a trip to Lewes for a long week-end to play music at a pub there. One of them was found standing outside having a smoke. On being told it was o.k. to smoke inside he replied "It doesn't seem right any more".
