For me, the biggie here is the DM. He hired a dive professional because he know he was at the edge of his skill level. I wouldn't expect a visiting diver to know exactly how difficult a dive site really is at a particular day, and to be safe he did the prudent thing and hired a professional, through the local shop, I presume. If I was in that position, I would expect that professional to be intimately familiar with the site, being able to judge the conditions and call the dive if necessary, and once in the water, being able to competently help with solving problems that are not completely unexpected at this site, like kelp entanglement. And of course give unvarnished advice when in his judgment my experience isn't up to what's needed to dive this site, on this day, with this DM, safely. Now, I would imagine that it would take a good amount of experience for any professional to live up to those standards. The minimum curriculum to become a DM certainly doesn't prepare one to do this at this particular site, and that's where I the shop's responsibility comes in: to vet the DMs they are using and referring on their trips have the actual - not just paper - qualifications for guiding those dives.
