Some Black people get off on subjugating White people.
Some Black women will keep a white waitress hopping for an hour and not leave her a tip. If she refuses to serve them, they scream "raaaaaacist"
Same with white nurses, some of the black women who are visiting a family member, order the white nurse around like their family member is the only patient that the nurse has to care for. If the nurse retaliates, she gets reported as being "raaaaaacit"
