Story time:
When I used to ride the bus into DC there was this smoker at the last bus stop. He always \'politely\' moved away from the line while he had his good morning smoke.
Problem is, he REEKED of cigs right after. Within a 6\' radius you could smell the walking smoke cloud like he was right next to you. So a long, comfy, expensive bus ride turned into pure coughing hell if you were lucky enough to get the last seat. The people in front and behind him also suffered. Whenever someone got off his partner quickly left him for the new opening.
Of course he didn\'t seem to give a damn. Just kept on smoking every morning. The people who created this ban were probably on that bus.
