Unfair Seating
My boyfriend at the time and I went to a high-end Italian restaurant once. When we asked to be seated, we went past two or three empty tables in a room that had people in it. We got seated in a back room where there were zero people and spent the next hour and a half dealing with slow, incompetent service. We were a bit concerned as to why we were shunned to this dark back room with terrible service.
It was the first time in my life I ever had to consider that I was being treated poorly because the person I was with was black.
