I doubt I smoked a full pack in my entire life, and that in the Army standing around, waiting doing nothing.
Furthermore, my parents, massive chain smokers, would take us on 4 hour car rides with the AC that only did the front seat going.
That said, a persons body and liberty are the ultimate capital. I don't support the WOD. However if an employer has a contract with you, well it is up to you, you have no right to HIS job.
Lastly, I hate wimps. A little smoke gets in you eye, or your fat, nosepicking spawn starts coughing up whole wheat latte all over his Diesel jeans---too bad. If your're that weak & sickly, lets get Darwin going and make room and do me a favor by dying.
