Portrait of a Cold Busker

Last day of the holiday today. Went into town for a bit of shopping, check out the sales - not much left, and not much of a sale either. Spotted this guy through the window of the coffee shop. After dropping some change in his 'hat' I indicated with my camera and he nodded. I took a few to start with, but he was obviously posing, after a while I stood off to one side and waited until he was doing his stuff without being conscious of the camera.
