5/29/10 *Survey* about air pollution, allergies, age of vacuum and cars.  No sales pitch given.  Although, did ask who I "get better service from when traveling - department stores, visa, MC, AMEX".  I asked what that had to do with pollution and he started to explain that they are just asking b/c...but then said never mind.  At first a woman called, but between her heavy accent and the noise in the background of her calling center, I told her I could not understand her at all.  She asked if she could call back and I guess I was feeling generous, so I said sure.  A gentleman called back, still with heavy accent and background noise, but was much better.
