This is really interesting and seems like a great example of how small businesses are better for their community than chains. When I lived in Fort Greene brooklyn I was surprised by how many barbershops and hair salons there were, like 5 or more on the single little triangular block at fulton and greene. It seemed clear they were providing more of a community function than just the utility of getting a haircut that i was familiar with. On a side note I never got comfortable with making conversation while getting my haircut and eventually settled on just cutting my own hair at home. That said I never tried the barbershop-type places and usually went to pretty generic haircut shops.
