Fish_Whisperer:Well... Yeah... It's actually a long and rather funny story. It turns out that one of the dive leaders got down to depth and realized that he had to crap, so he surfaced and the boat took him to shore. Then the boat came back and dropped him off with his team. Meanwhile, being the airhog that I was, as a n00b diver, I had surfaced to find that there was no boat. I bobbed around for about a half hour, and another boat came by and circled me, after radioing my boat to come get me. (And they had been on their way to do just that, apparently.) Seriously, they were a fun and good outfit to dive with, but for that one incident.
Sure, only one incident, but it is a doozy that indicates a real procedural problem.
