Oh I'm not surprised. When I was 19 years old, I spent 3 months in a homeless shelter. I had a group of weird Latina and black women look at me like I was garbage. Later on after they came to know me and like me, they apologized for thinking I "looked like a Nazi" when they first saw me. 

How did I "look like a Nazi"? Because a lot of people know someone of ethnic German background when they see them.
