Peter P - your experience of grateful clients doesn't gel with mine. In some 14 years in various S&R versions, I can only recall one brief phone call from an unidentified 'client'! Indeed, even when the customer was a serving Senior Officer, our reception on task was bad tempered and not a hint of thanks subsequently! It was never a problem because the job was enjoyable and its own reward. I suspect that in most cases, during my time, the civilians we picked up were concerned at the possibility of being identified and charged for the service. We didn't, of course, although towards the end of my time, inter-hospital transfers were being costed and charged.
