And it is not just fellow divers. I get particularly annoyed by DMs that try to insist on setting up my gear or make changes to my gear without me asking or knowing. On a recent trip to Maui, a DM told me that his boss insisted that he set up all the gear and treat every diver to valet service whether or not it was requested. I told him that since I was going to be the one tipping him or not, he should pay attention to what I want him to do. Another DM in Fiji changed a setting on my camera without my knowledge or permission because he thought his settings would give me a better photo product. As a result, he switched me from RAW/Aperture setting to the underwater setting, and I did not notice the change until I loaded the pictures in my computer only to find I had only JPEG files and no RAW. Maybe if I was a more competent photographer I might have caught the change, but that was the last thing I expected from a DM with an expensive camera.
