If indeed he saw correctly that you were low on air and ignored you, you should at least have reported him/her to the dive op.
Seriously??? You would report the DM for what? This new diver was running low on air. I think that the DMs responsibility at that point is to insure he heads up and surfaces safely, but he (the DM) also has the responsibility of the rest of the group so he can hardly drop everything to tend to this one guy, who was ended a dive normally, albeit early. The Divemaster is a Divemaster... Not a nanny for crying out loud.
I hung up my teaching credentials a few years ago, but I keep reading about people who bought a C-card but really have no friggin' idea how to dive. I just came back from Belize where I crossed paths with a family (Mom, Dad, 2 teenaged boys). They had been certified a year before in Cancun, at I assume, Juan's Discount Car Rentals, Tacos and Scuba Diving Lessons. I say this because that the end of our second day of diving together (same day, same ocean, but no where near them) they were filling in their logs and were debating how deep they had been and so on. I assumed that they, being newbies, perhaps weren't aware of the log function on their computers, so suggested they could retrieve the pertinent information that way. That's when they told me, matter-of-factly, that none of them had a computer or depth gauge, only one had a watch and none had ever even heard of tables, let alone have a clue how to use them. This led to a conversation where they confessed that they simply stayed with the DM and figured all would be good. I should perhaps add that on this day, we dove the Blue Hole and then two other dives. My guess is that their profiles were roughly 145'/40, 100'/50 and 80'/50....
As the discussion progressed, it became apparent that they had absolutely no knowledge of DCS, its symptoms or the seriousness of it. And as if that wasn't enough, the eldest boy (18) then mentioned that his shoulder had hurt at lunch (about 90 minutes after the second dive), so he had gone to Google, self diagnosed "the bends" and developed his own in water treatment... He stayed shallower than the DM on the afternoon dive and stayed as long as he could at 20' at the end of the dive. Amazingly, he was feeling ok!
Anyway, I don't want to derail the OP's thread, but I thought it was important to point out that now, more than ever, a C-card is almost a meaningless piece of plastic.... At least in some cases. Apparently, Juan's Taco Stand and Used Car Emporium was also a PADI 5-Star Facility. And these weren't morons... Dad was a lawyer, Mom was a teacher and the kids were doing well at school. But they had no idea how to avoid killing themselves, and hadn't mentioned to the DM that they lacked computers.
