Hey Sherman this issue came up before. If you look at Jimbo's reply you'll probably have your answer.

ch0ppersrule:i had a tank for nitrox that certain shops wouldn't fill because they weren't 100% O2 lubricated/cleaned. The dive shop that prepped my tanks for nitrox went out of business. I just made my tank reg air ready now.
soudan:did you have the Visually Plus done on it?
the Visual includes the inspector looking inside your tank making sure your tank is corrosion free, and changing the O-rings and putting silicone grease on them.
the PLUS is something called EDDY CURRENT TEST which is a test to the neck of your tank making sure no cracks are available in the neck of your tank. a threaded plastic device is screwed where your valve goes (on the neck) then it tests. eddy current tests by sending electromagnetic waves to measure certain material characteristics of metals, therefore showing internal cracks that you will not notice with your eyes.
some shops will not fill your tanks because there was no Eddy current done on the tank and if any thing might happen to your tank (explode) while filling it up in their shop than it is a danger to them.
I am guessing that is why they didn't fill it for you.
rockjock3:On that note. Does anybody know why no shops on the island bank 32% and 36%nitrox? do they know they would probably make a lot more money selling it if they did, since people wouldn't have to have a pair of dedicated tanks and wouldn't have to pay $12-14/tank for nitrox? Heck I would pay $6-8 a fill if I could just use my regular tanks, but I as much as I like to use it I don't that often, due to the cost and inconvenience of having to go and rent tanks and then return them again later.
Hint, hint for you LDSs out there on Oahu.
fishb0y:Yup, sounds like OC to me... Totally clueless... I planned on bringing a steel 72 to them to see what they would do
