I'm a non-smoker, and I couldn't care less if smokers want to puff away. My only concern is that I don't want to be exposed to the second-hand smoke. If smokers can do the deed somewhere where I don't have to suck up their smoke, more power to 'em.
Here in Florida, smoking is illegal in just about all indoor areas (excluding homes, of course). I love it, but sometimes have to be reminded that it's not like this everywhere else.
