I tried this place out a few months ago, and typically get a shaved head with a manual razor blade. The normal, older barber I see is really good. We're talking about 4 star territory here. His razor skills are amazing. But I only knew that his skills were amazing until today, when I decided to use another barber (since my regular barber was on vacation).
Imagine someone has a razor blade shaving your scalp, and is pressing the blade so fiercely and at such a bad angle that the blade cuts through your skin. It hurts. Now imagine this happens several times while you are trying to remain calm and composed in your seat. After reacting each time he cut me, the guy didn't even change his approach. He was also clumsy, and came close to shaving off my eyebrows.
I must admit, I made a mistake by staying in the seat after the first laceration to my scalp. That said, I have been to other barbers where it's just one nick, and they adjust their approach. In any event, I am paying for my reluctance to simply walk out of the place or to switch to another barber in the same establishment.
At the end of this ordeal, I ended up paying my fare, having the cashier say "sorry about that," and telling my barber "you get no tip." The barber just stood there, listless, as if nothing had happened. You know it's a bad shave when you have onlookers (the cashier) apologizing and the barber saying nada.
That said, I am totally fine not to have engaged in any argument about how bad of a job this barber did, how the place shouldn't hire barbers like this, or how I shouldn't pay for my shave. Instead, I will vote with my wallet. Never going back here ever, even though I like my regular barber. I average a $5 tip and $20 haircut twice a week, so that's only about $2,600 / year this establishment will lose by allowing such an incompetent, untrained barber to be working there.
Overall, I give a rating of (a) 4 for the good barber, (b) 0 for the crappy barber, and (c) 2 for the establishment for hiring crappy barbers. A total of 6 points, averaged over three criteria equals an overall score of 2.
