For years I've went through dozens and dozens of different barbers and hair dressers trying to find someone that didn't charge my wallet until tears of misery rolled down my cheeks and still did an excellent job.
I will not lie, I am VERY picky with haircuts (and I do not trust myself with anything that is sharp, including electric razors even if it is hard to screw up with).
I, Mihai, after 14 years of going to different barber shops, have found my messiah. My savior by the name of "Mitch" charges me only 18$ (which I always give him a tip on, which he very humbly accepts) and cuts my hair to perfection. Not once have I ever left his domain disappointed. He's also always up for a nice chat, provides good feedback, has tons of knowledge that he shares willingly and works there 6 days a week.
The shop has other barbers too but I believe in loyalty. Mitch has been cutting my hair for the past 4 and a half years and I'm never going back to a service of lesser quality as I have experienced, here, the quintessence of hair cutting.
I do not know about the proficiency of the other barbers. I can only vouch for Mitch's but the majority seem quite competent and friendly.
