Anti-smokers are the addicts..........they have no concept of reason and thus act accordingly.
Here is one that would really drive you nuts. I know a guy who would make a big deal of hacking whenever he SAW a smoker. We were at the mall once and I had seen someone smoking across the food court. The person was behind him. I had noticed this for at least five minutes. It wasn't until the guy turned around to get up that he started hacking and coughing about the cigarette smoke. It really was irritating.
