Another funny thing that we saw by the Trevi Fountain were the street Vendors who sell knock-off purses, belts, etc. They lay their things out on sheets and harass everyone who walks by. Alexandra actually ended up buying two fake Gucci purses though. It's actually a very good deal if you haggle with them since the purses are actually very high quality and look very nice. She managed to get 2 for only 25 Euro. The funny thing is that when the cops walk by all of the vendors just pick up the sheet with everything in it and stand there until the police pass by and the moment they walk past they lay it down again. Not after they are out of the area, but seconds after they walk past. There were two cops walking back and forth around the Trevi Fountain and all of the vendors just constantly picked up all of their stuff and then set it down, and picked it up and set it down, and picked it up and set it down. over and over and over. It was really funny. We stood there and watched for about 5 or 10 minutes. Another strange thing about the vendors is that it is mostly the black guys selling purses, the middle eastern looking guys selling toys and other little junk, and in Milan it was asian women selling remote controlled cars.
Here is a video that I made of the vendors picking their stuff up as the cops walked by: http://www.youtube.com/watch?v=CvVon3wqW8Q
