My county is 2% black, and the only black I know socially is an upper middle class Republican. The only service person I have dealt with who is black is someone who works the men's suit department at Nordstroms. He is the guy I buy my threads from.
Word. Which county are you in? I probably win when it comes to dealing with blacks, as Charleston county is nearly 40% black, although most areas are highly segregated still, except for the mall.
Orange County, California. The place has no poor black neighborhoods, and the bulk of the blacks there are middle class. Hispanics do the heavy lifting.
