Black people have different hair than other races so it requires a specific skillset not all barbers have aquired. Also the black American community puts a lot of value in their haircuts. Because of that black barbershops are not only a place where you get your hair cut but also an important meeting place in the community with huge cultural importance.
Btw I’m a white German who’s never been to the US who got all his information about black barbershops from media so if someone better informed than me chips in I’d rather listen to them than me if I were you.
Did you take a look at the cabin? Seems in line with something like a private jet.
