Back in the early 80s, we were called to the cliffs near Bondi to help 2 rock fishermen stranded by rising tide, big seas, and approaching nightfall. We were able to find a flattish rock to land on and loaded them into the cabin for the 400' climb back to the top of the cliff.
A month later, another call to the same area. We land, get them on board again in the same fashion. The crewman looks at the men, says "You're the same ****s that we picked up last month! You haven't learned a ****** thing!" , opened the door, and threw their gear into the sea.
