Miss Jones Approves: Lefty's Barber Shop, San Diego
The owner at first glance has the clean-cut barber look of the 50s. Perfect shave and haircut, black slacks, white barber shirt. On second look you find sleeve tattoos, the hallmark of the rockabilly/sick boy. What's that? Google Social Distortion.
I would think that an old-school type of barbershop would be a big hit with men: a full range of classic services and technique, male camaraderie, and shooting the schitt... just like it was when grandpa took you for a haircut. More than the nostalgia, I'd think that the very basic approach would be refreshing. Plus if you'd want to try out a classic look, I'm sure they could help you with that.
There are a lot of people out there in my age group who love the "old ways" of doing things. And I'll attest, we actually do love it. Doing what you love for a living can never be topped. Unless it's a high top, or something like that :)
