Seeking Converts

We're used to Jehovah's Witnesses ringing our doorbell at home from time to time, in the vain hope of engaging us with their message, but I don't think I've ever seen them setting out their stall on the high street.  I'm not sure how successful they will be in this location, but you can only admire their persistence and smart appearance.  Rather incongruous amongst the more casual clothing often seen on the high street these days.
