One of my co-workers (our receptionist) smokes. On Thursday's and Friday's when our part time receptionist is off I'm responsible for covering the phones when this girl goes for lunch or out for a smoke.
Today, when she informed me that she was headed out for a cigarette I told her
"Girl, you're gonna die if you keep doing that."
She replied with, "If I don't go, someone certainly will die". She's a bit stressed right now. You can't really argue with her logic either :D
