On a recent trip to Cambodia I passed by a barber on Street 240 Phnom Penh near my hotel. I approached him and pointed to my camera, he smiled and nodded while pointing to a sign saying “$1 haircut”.
I love the simplicity of his operation; it’s like a “pop-up store” that can be taken down at the end of the day. No appointment books, no computer screens, no garish hair products on display. It’s just him on the street armed with some scissors and a mirror.
