You and I both! I think that there are simply divers who have been doing it so long they forget the ocean isn't theirs solely. Standards do change and so what? No one is going to have the buoyancy that another person with 1000+ dives is going to have except someone else with that many dives. I'm just glad that when I was a noob that no one berated me because I was "simply an OW diver".
A question on the DM test I took Thursday night was something along the lines of if you are a DM on a boat with TECH DIVERS what would you NOT do? One answer was turn on their air for them. Of course, that wasn't the correct answer (I got the question right...) but my instructor thought my comments about the question were interesting. I said, based on some of the things I've read on SB, I doubt I would touch a tech diver's ANYTHING unless they specifically asked for it. We talked about turning on air as a DM "service" but I pointed out that tech diving, to me, equates into someone who is probably waaaaaay more experienced than me, and would probably label me as an inexperienced DM if I touched their equipment. Besides, I believe they take extra gas down with them, probably don't want some of them turned on.... and my instructor agreed.
