A white woman in St. Louis got fired after she tried to stop a black guy from entering the building they both live in. He filmed the whole thing and posted it online.
First she tries to block him from entering the lobby, then follows him upstairs in the elevator, until he unlocks his fourth floor apartment. It's impressive how polite he is, how stubborn she is, how she tries to make it seem he pushed his way in, then tries to justify that what she's doing is the right thing.
