I suppose all the whingeing from smokers about 'freedom-of-choice' etc. is inevitable. But as I see it this is a blow for freedom for all of us who hate having their 'sensory spaces' invaded! Now how about banning yobs who drive around in summer demonstrating their appalling tastes in music at ear-splitting volume (I think you should be able to toss a tear-gas canister through the open window) and women who drench themselves in sickly perfume and introducing swingeing and rigorously enforced penalties for dropping litter and fly-tipping?
