I am surprised at having read this thread. In December me and a bud (he posts here by the handle lanmonkey) did 10 dives each with Island Divers, and had a completely opposite experience.
They had us fill out a liability release for every dive outing (we had different DMs and the dives were spread out over the course of a week), and for the first set of dives carded us (asked for c-cards).
Looking back we did 4 dives with Ken, 4 with Matt (shop owner), and 2 with Jo. Nothing but smooth sailing the whole way (until the weather got rough and the last two days of diving got cancelled).
Buc, your assessment of Island Divers couldn't be more wrong. Who gave you that info., another shop?
Island Diver's shop is located on Hickam AFB, at the poolhouse. They've got probably over 100 tanks (dunno how many exactly, but they had a hell of a lot when we were there) and also offered Nitrox for those who wanted it. Limited selection of dive gear in their shop, but they were more about getting divers out on trips than selling gear (that's why their prices are lower - little in overhead gear inventory costs).
I never had to get a ride from them (we had a rental car) but usually when the van rolled up to the dock they had a few divers in tote that they had picked up at places around town.
From the viewpoint of a dive pro myself (DM at the time, now AI) I thought Ken was very thorough on his dive briefings for the sites (we did the Corsair trip with him, then a second night trip to the Sea Tiger). Explained procedures, dive times, fish to look for, etc.
On the Sea Tiger dive, he stayed at the mooring line with an artificial sun (one of those high powered UK light cannons, but if you've seen one UW you know what I'm talking about) so we knew where to head back to.
The second dive we did that night was on Kewalo Pipe. He led the dive down the pipe (seaward), and when the first member of the group hit 1800 he turned the dive back up the pipe to the mooring line.
There was a member of the group who was doing his first night dive, and he kept that buddy team with him at the front of the group on the pipe, just to make sure the guy was comfy (they also didn't stray too far from the line on the Sea Tiger).
I'm sorry that you had a bad experience with Island Divers on your trip, it sounds like Ken may have been having a bad day or something, he was top notch on our trip.
Similarly, I'm not sure what happened on the phone when discussing your dives. Max usually handled the actual bookings and charges, etc., are you sure it wasn't him that you had your "disagreement" with?
Matt is the owner, and he seemed like a good guy around us. We shot the breeze with him at the shop on two or three occassions, and he also went out on two trips with us (Sea Tiger day and Black Rock day), even had his wife and parents with us for both trips.
The shop just got up and running in the last year if I remember right, but they seemed like they had their stuff together.
At any rate, sorry you had a bad experience, but I just wanted to put in two cents on the other side of the coin. I do agree with what others have said here though...
* develop a relationship with your buddy for the dives. I've helped certify about 500 divers now, and my experience is that when strangers are first paired together, there is often an initial moment of hesitance/resistance to someone new.
But once they extend their hands, shake, and introduce themselves, and start talking, you'd be amazed at how friendly they become. It's easier to break that barrier with something in common background wise, and guess what - you're both divers!
Some friendly "so, how long you been a diver?", "done any other dives down here (HI or wherever)?", "so where else ya been diving at?" is a great way to break the ice.
* take care of yourself first, both WRT assessing if you really want to do the dive and also to taking care of your safety on them (this ties in with having a relationship with the buddy, whether they were "friendly" or not)
* don't be afraid to talk to the divemaster if something doesn't sound right, or you don't feel right about something. Just don't confront him in front of everyone. Tell them you have something you want to talk to them about in private, say "hey, can I talk to you for a sec", whatever you're comfy with
* practice your buoyancy skills so you can hover midwater away from objects (like say a descent line). if there's not a lot of current, you can usually just hang out and not have to worry about the surface chop bouncing you up and down on the line)
* go back to Hawaii again and do the Sea Tiger, it's an awesome dive! (easily my favorite dive in Hawaii... can't speak to Kauai yet)
