I can say the whole rigamarole shown in the clip isn't even a uniquely race thing.

I've seen plenty of my white trash friends and relatives go through similar "passive aggressive trying to get rid of you." Its a class thing, with the general assumption being that the poor and/or less sophisticated will bring trouble and aren't even worth associating with, but you can't outright tell them to leave without creating a scene. The problem of course being, every black person looks poor and/or like they will bring trouble so it is a much more common thing on their end.

I don't even blame the people for doing it, because most of the time they have good reason to do so and not a lot of reasons not to prevent the risk.
