Making a statement...

Several of the expats here have mentioned seeing this, but I actually saw it for the first time yesterday.  First some background.  The wearing of surgical style face masks is very popular here.  The idea is to keep your lungs clean and healthy.  So what king f statement does it make when you see a man pull his aside to take a puff off his cigarette?  Just how bad is the air in Shanghai?  Wish I had caught a picture of that.
