@Blackfist I'm white, but this does ring bells. First was in North Carolina, during a working break from Uni in California to see the South. Stopping at a bar near a local college with a black friend, he refused to get out of the car: "I can't go in there." Then much later incidents at that level and higher, mostly involving my wife from Japan. She passed away this year, but those experiences and the better memories remain. It's targeted, you can stand next to the person and not notice.
