As a non smoker, I'd probably revoke the smoking ban.
It's pretty much wrecked the pub industry in this country, along with cheap beer deals in supermarkets, honestly, who's buying 4 pints in the pub, when you can get 24 cans at Tesco for the same £10.
Really tho, since the smoking ban most pubs are either empty, or they've turned into a Starbucks style bar/restaurant/coffee place.
To me, the idea that people go to a place to drink poison, sometimes in the hope of getting to talk to someone of the opposite sex and take them home for some drunken unprotected sex, (and condoms are so much more likely to be forgotten about after eight pints), that's fine, but nooo, you can't have a cigarette is a bit much.
that or revoke all copyright laws for a day, see sales of music/movies/games/etc not change in the slightest, and then just smile smugly to myself, as mere evidence won't change any minds at the top of the food chain.
