This is actually something that irratates me, simply because smokers are made out to be the root of all evil by the media recently, if many were just more considerate and stuck to some rules like i try to i don't think people would think it half as bad. i.e, don't smoke while people are eating its just nasty, if your with people you don't know and you can see none of them smoke ask if they mind first don't just light up and hope they don't and don't blow smoke towards people, even i find that annoying and finally don't smoke in peoples house's unless they do.
To ban smoking in public places is
imo an infringement on my human rights (taking it a bit far i know
) and some could argue that me smoking is an infringment on theirs.
Besides i think in certain public places like pubs and clubs its to be expected, don't go in a pub if your gonna moan about smoke its just pointless
imo i know i never did when i didn't smoke, it is by far the least annoying thing in a pub when compared to the 5 drunk twenty somethings in the corner laughing in possibly the most irratating way and shouting/singing at the top of they're voices.
