I was on holiday at scarborough last year, catching crabs off a jetty. There were a few people doing it, well the end of the jetty was very slippy, and a little girl walked down it, slipped, hit her head on a metal bar and fell in. She was almost unconscious when i pulled her out of the water, on my own -(because some tw*t just stood behind me shouting "she's fell in!"). So yeah didnt really save her life but her mum was grateful & gave me a £5
