Were you expecting something better because you're a "white European"? I don't really get why that prefaced the story. I'm not white and I've never had such a bad experience as you in any country, let alone America, am I doing something wrong?
How would it be if I visited wherever you're from and proud of, and intentionally stayed in a terrible part of town and got around by bullock cart, and then went back to America and bitched incessantly about your shithole of a country?
