>>>I don't dare take a puff while even in the parking lot. <<<
Before I retired, a co-worker and I were sitting in his office about an hour after close of business. We'd been caught in a verrrry loooong and booooring meeting. The company had campus-wide anti-smoking regs. All of a sudden my co-worker began sniffing the air. Then he picked up the phone, called security and complained someone on the floor was smoking cigs. He actually met the guards at the entrance and accompanied them on a hunt for the perp. It was another guy who'd been stuck in the same meeting, was clearing his e- and phone mail, so he wouldn't have to do it in the morning. I can see how the "stitches for snitches" thing got started. Granted, my co-worker was the dept drama queen. And granted the HVAC system was awful. It circulated internal air, but didn't bring in fresh air from the outside.
