Smoking Kills

I realize you are a senior citizen and set in your ways, but the stench of stale cigarettes coming off you is going to kill me. Can't you see how I am clinging to the edge of my seat contorting my upper body away from you in a futile effort to refill my lungs with fresh air? Second only to stale urine (another all too frequent commuter encounter,) nicotine and tar-infused wool -- er, wet wool -- is highly offensive. I also suspect this particular gentleman has not brushed his teeth in a while. Well, at least it does not appear that he is incontinent. That's a small favor for which I shall be grateful.
