Being from a country no one gives a fuck about, I have experienced the sort of "discrimination" described many times. Banks, ISPs, stores, local ad users would just refuse to sell to me. It's a sad reality, but a reality nonetheless.
I still remember a needlessly lengthy email from an incorporation service explaining to me the difference between "lawyer" and "attorney". Seeing as I learned English from TV shows and the Internet... I still don't get why using the word "lawyer" got them so offended :D
