A few years ago I was up in Scotland diving around the Isle of Mull took the boat back in to Tobermoray harbour after a days diving and pulled alongside a steel mesh jetty. Stepping onto it it started to tilt and I got my foot wet but managed to climb over it. A little while later myself and my diving buddy were having a pint leaning on the rails watching over the boat when a Yachtie aproached the same jetty in a small tender. Stepping off onto the jetty he put his full weight onto it and immediately toppled over into the water!. He didn't look very amused at the loud hoots of laughter coming from the quayside above
