There was a joke at my high school about kids robbing the Guatemalans that lived in West Palm Beach. They thought it was funny that the Guatemalans were illegal so basically always carried cash on them and were walking atms. This sort of thing happens because people don't speak the language and don't associate with the right people. I will completely agree that an expat will have a harder time than a Dominican most of the time because of the language barrier. Also, by virtue of skin color and floral bermuda shorts, some expats shout "rip me off" at every corner.
