Second hand smoke is absolutely nasty stuff. I avoid it at all costs. A few years back I was working for a company that prided itself on being a
health care company. In addition to junk food and sugar drinks in the vending machines, they also provided a smoking area right outside the back door which was the entrance to the building from the employee parking lot. This meant anyone using that door had to walk thru this crap, then touch a doorknob that was opened by someone who was just holding a filthy cigarette a moment earlier. After entering this doorway a few times, I decided to walk around the building and use the front entrance. This took about 5 minutes extra, but I always made sure to do it on company time!
