Dude! You can't just come on here all bent out of shape about a bad dive in Hawaii, make a fuss about it, then not even mention which island or operator.... It gets people riled up. You said "EPIC FAIL" yet YOU failed to let us know what you were all upset about. There are 8 main islands here that have all types of diving available. See how people reacted to your first post? Then you come on talking about how the "Best Option" was booked (we can only guess who that might have been) and then you say you got a mediocre dive at Molokini. Come on, throw the readers a few more clues... there could have been MANY reasonable reasons that you got a dive that didn't meet your expectations. Simply walking without leaving a "tip" might not have done much good either (except to make you feel better).
Did you also ask for the Back Wall when you boarded the boat that morning or was it something the booking person promised you? (That can make all the difference right there) Who else was on the boat besides this snorkeler? Were the other divers as competent as your family? What was the explanation given by the crew? Where was dive # 2?
The Back Wall is one of those dives that gets mostly over rated if you ask me. Yes, it can be an AWESOME dive. It can also end up being a disaster and everything in between. Many divers consider it a "HOLY GRAIL" of Maui Diving kind of thing and when they do it and if it's their first back wall dive they end up having issues like : Changing Current, Low Air, Rapid Air Consumption, Bad Ears, Poor Bouyancy/Lack of Bouyancy Control/ Rapid Depth Changes Due to Vertical Currents, Diver Separation, Difficult Live Water Exits, etc, etc. I have made many back wall dives as a "guest guide" on several of Maui's BEST Dive Boats. I can tell you from my experience that MY Back Wall Dives are NEARLY ALWAYS CUT SHORT "thanks" to the other divers that dive it with me. If you really want to get the most out of that dive, you are as experienced as you say, and it is as important as you indicate that you accomplish it then I would HIGHLY RECOMMEND that you get a PRIVATE TOUR of it.
So, I'm sure everyone (myself included) wants to know: What did the operator say when you complained?
Here's a little something~something I made up about the Back Wall. Have a look see if you have a few minutes to kill and good luck next time...
