ahaha
look i dislike smokers lots and its really their own fault for the
sort of inconvenience they have to face. Nobody FORCED them to take
up smoking, and the help to quit is always there. Look at Bear, an
ex-heavy-smoker. He say stop almost immediately stop. Willpower,
everyone has it, just whether u choose to use it.
But in this case, if non-smokers are STUPID enough to sit in the
yellow boxes...... and breathe in all that 2nd hand smoke......

Still, if u cannot sit elsewhere n control your urge to smoke for
like, 5 mins, until there is space freed inside the yellow box, u
do have a very serious problem.
