I believe this happening, and given the amount of news I've seen at the moment, I can't see that racism is improving in the US right now.
Mind you, I've worked all over the world, and perfectly lovely seeming people can come out with some gobsmacking stuff when it comes to other races to their own - I've watched people be horribly rude to people because of their race, and then turn around to me and be sweetness and light over the same issue. I've seen adverts specifying which types of immigrants are allowed to rent a flat, and I've been rejected myself because I wasn't the right race.
When you then intersect it with sex, well, we all have so many stories of people not believing us when we say something don't we? Especially professionally - I've lost count of how often I have to assert myself in ways that the men around me don't.
I bet she's not getting a decent apology/thanks either.
TBH, this is why I'm resisting moving to the US, and given any other choice, don't fly on a US airline.
