Many years ago I was in Richmond and a 'Little Old Lady' (Well a very fit 30 something as it happens) locked herself out of her Mini. I said, I can get it open for you with a piece of nylon band tape, hang on I've got a piece in the car... PC Plod came past and was not amused! 'Wot you carry that for them?' Answer, I had a case of 12 Bore shotgun cartridges I had just picked up from the gun shop taped with it. 'Err, wheres your Shotgun Certificate then?' "In my pocket as it happens" and so on.
