I really wonder where all the fake-spotting takes place! Usually people are walking too quickly to catch more than a glimpse of their bag. And if I was in a cafe or wherever I would never draw attention to myself (or broadcast a lack of manners) by staring at somebody's bag. Having said that, I once saw a student waiting at the University bus stop, and carrying a blatantly fake Balenciaga First. These sorts of sightings are rare for me though. The most blatant, rubbishy fakes I have ever seen were being sold by pavement sellers in Italy last year.
