I've seen these little carts before selling horrible fakes. If I am feeling particularly ballsy, and if the salesperson looks like they are easily intimidated, I approach them and do some "educating." That basically consists of the "why fakes are illegal, bad, tacky, etc." speech. I also report these shops to LV's legal dept on vuitton.com or to a manager in the Customer Care dept at 866-Vuitton. One time in NY I got soooo pissed at a mall vendor who was selling fakes that I called the police and filed a counterfeited merchandise report, right there on my cell phone, while I was standing right in front of their stand! I might have ignored him and laughed at his stupidity, but I overheard him telling people that his items were real. The audacity of him! UGH!! It just makes my blood boil. Who knows if the cops took me seriously... lol... but I felt that it was my civil duty to stick up for LV.
