Several years ago, when I was a visiting professor in Istanbul, I had been "in-country" for six weeks and really needed a haircut. None of the other faculty lived near the University, so they couldn't give me a steer to a good barber shop. I went out one day looking for one. I just walked around and looked at several. I came to a shop that advertised pedicures. I decided that one wasn't for me. I finally found one that looked just like my Dad's old shop. He would have felt at home in it, and I got a good haircut, among male barbers and male customers.
