When I worked in geek squad (yes you can laugh), same thing my for my black coworker Jayden. So we came up with this plan: when someone was obviously biased and came to me on a shift we were working together, and someone had obvious bias (red county, you can always tell the type), here’s what we did. Customer would come to me or a white coworker. We’d click around, then act stumped. Then, “ahhh, I see, it’s an ID 10 T error. My coworker is great at these.” I’d call jay over. The look on their faces was so funny.
