I try to avoid being "hearded". Once in Venezula, my buddy and I were the only ones on a particular charter. The dive was around a small island (or large rock). The DM wanted to take us around the rock and see all the sites. My buddy and I said, "No, we wanted to take our time and take pictures. There is no way that if we do this we can make it all the way around that rock." Well, we got in the water and the DM proceeded to swim full out around the rock. After chasing him for the first few minutes, we just abandoned him and made our dive. The only problem was that when we came up the boat was around the other side of the rock waiting for us there. They did finally figure it out and save us from swimming the rest of the way around.
Another time in Cayman I was on a boat with several other divers that I did not know. My buddy was sitting this dive out so I was the odd diver on the trip. When the DM could not find anyone to volunteer to buddy with the photographer he said that he would buddy with me. He let me do my thing and stayed relatively close to me. During the dive I noticed that I was adding air to my BC more often than I should have been. I thought it probably was a leak in the BC hose or BC where I could not see it, but it was small so I was not really concerned. When I got back on the boat I found the connection between the corrugated hose and the BC was slightly loose. I fixed it and mentioned it to the DM. He said, "Yeah, I saw that it was leaking." Now, I ask you, wouldnt any decent buddy, not to mention a DM, have come over and tightened up the coupling? Now, I recognized what was wrong, recognized that it was not serious, and went on with the dive anyway. I could have stopped and taken my tank off and fixed the thing, but isn't this the kind of thing that a DM is supposed to be there for?
