There’s no requirement, and there’s no reason a white person can’t go to a black barbershop, but black people’s hair is often much different to cut than most white people’s hair, and preferred styles quite different.
It’s not so much “this barber is for black people” and more so “this barber is owned by black people, so black people can assume they’ll be given the experience they’re looking for”
“when they think you’re gross”
How can I know if someone thinks I’m gross if I haven’t spoken to them yet? I should just assume I’m gross, always?
