The one whose own hair is a mess because we know that a good Barber never has time to do his own because he has so many satisfied clients. Truth is, he probably cuts the person whose hair is so perfectly groomed.
The groomed one, because they are both skilled workers, however variant in style, even if they cut each other's hair, what are the chances they might be sleeping or not bothered while their hair is being cut.
LOL, Beth! Yes, well...in these days of "unisex" everything... who knows. The sister of a very good friend of mine is a barber, and she runs her ownbarber shop! She never wanted to work in a beauty salon, as she has no use for all the drama that can be found there.
