Alright gang, let's try another way to get to what the diver should expect from a DM...
What should the DM be able to expect from the DIVER?
Should the DM be able to reliably assume any skills from a diver?
Does the diver have any responsibility to take care of his own rear end?
Does the diver have any responsibility to make any decisions?
Or does the diver's responsibility end when he pays for the dive?
When a diver remains on the surface after the DM takes a group down, should the DM abandon the group to "see what's wrong" or should he expect the diver on the surface to have enough sense to stay there?
Remember, we're talking about certified divers on a guided tour here, not an instructor with a class.

Rick, we can certainly discuss a diver's responsibility to dive safely to his/her level of training. Certainly this should be expected. I don't know about you, but I do not take a C-card as my only yardstick to assess my level of confidence in someone's ability. Far from it.
Should a DM:
a) Assess if a diver possesses the requisite qualifications and experience to perform the planned dive?
b) First insure that divers are qualified for Nitrox before giving it to them?
c) Assign buddy teams?
d) Provide a safety briefing?
e) Check equipment before entering the water?
f) Record tank pressures and in/out times?
g) Take reasonable measures to insure diver safety?
I'm afraid too many DMs feel that they have
no responsibility for anything other than to act as a tour guide. This is a mistake.
Should a DM go to a diver struggling on the surface without a buddy? Absolutely! Even if he only escorts him back to the boat. Does this cause inconvenience to the other divers? Sure; so what? A few minutes shouldn't make much difference. When other divers realize that this is how Clients are treated, they can't help but appreciate that if it was them, it's what they would want.
I remember the day when I could dive with my buddy without anyone holding my hand. It was when I was 12 years old and first certified... What is happening to diver training when a DM is required to supplement for basic ability and knowledge? It seems that something is being missed here.
