gravy posted...Besides, saying the smell bothers you or having to have second hand smoke? Do you drive a car? Those emit fumes that smell and are toxic to those around you. What about when people fart around you? You're pushing poo particles into the air when you fart...GROSS.
The key difference being that smoking is voluntary and serves no other purpose. Cars are pretty much necessary in most cities (and there are plenty of initiatives in progress to reduce their impact on air quality). Farting is a natural consequence of bacterial activity in the gut, and typically can't be controlled (and when it can, those who choose to fart around other people are in fact being highly inconsiderate). Smokers, however, are stinking up my air with their choice.

Given that you're the one creating the smell, it seems far fairer for you to walk away until the smell stops bothering them. Expecting people to go out of their way to accommodate your voluntary smelliness is hardly reasonable.

Then I'll read their minds for you: Nobody likes you. At best, anyone who isn't lighting up beside you is ambivalent, but most would rather you not smoke around them. Given that, coupled with your inability to tell when people are allergic, asthmatic, or otherwise particularly sensitive to smoke, choosing to smoke around anyone else is impossible to defend as anything other than a dick move. Just don't do it.
