Surprise: If people are smoking on the patio or sidewalk, the air there is just as bad as it is in the smoking section indoors. Huh?

Otherwise, a nearby outdoor smoker pollutes your lungs as much as an indoor one. Next question: Which is worse? Spending a few hours in a car, windows cracked, with a smoker -- or sitting through a couple of jazz sets in a smoky bar. Answer: The car. Even with the windows open a bit, it's worse than the smoke-filled bar. So the next time anyone asks, don't think twice about saying, "No, PLEASE don't smoke while I'm around." |
