Of course it is real. Was that a serious question?
I guess I just can't wrap my head around such bias. As I said, I will take good service without ever caring what skin color or religion the person delivering it is. I can't fathom why anyone might prefer inferior service just because of such things.
Some of the videos I share the most with people are talks by Daryl Davis. While they are all very similar, I sometimes watch different ones, and recently watched one he gave 2 years ago (with a Q&A session) at Google's NY offices. The only thing I find that I am consistently in disagreement with him is his choice of attire.
