They're both in the wrong. The white dude started the whole altercation by being rude in the first place, but there was no need for her to overreact like she did and give off that much of an attitude. I understand checking the guy for being rude, but she could have moved on from it after getting her point across.
He can't be victim in this situation since his actions lead to the whole thing, but there's no way she should get a pass either.
