I went to a white salon once and they did a pretty good job. Of course, they didn't call it a doobie wrap, but that's what they did. They gave me the best trim I've ever gotten, though.
My mom has a short natural for years, and she would go to Supercuts in a pinch sometimes... it wasn't as good as the barbershop, but they did alright.
...hopefully, the next time I go to a salon will be the last time for a while... I'm starting my locs!!!
