FLGunner, JW652, RCS9250, Chickenthief, & FW-190, et al. Thanks for taking the time to read and respond to my questions about this matter. They were very helpful and greatly appreciate the brain trust of forum members here. I did finally get to speak with the dive shop manager and was informed that this shops oxygen fill area is in a completely different area of the shop, apparently located behind her office. And that none of the fill in staff members are allowed to conduct such fills. Of course that doesn't mean someone can't attempt it, but extremely unlikely. Also the reason suffer dude wasn't able to get it up to 3k psi was that the air banks they have were low that day and would have been impossible to do a >3 or 4k psi fill until they replenish them.
I apologize for the false alarm, but I really had no idea what was going on, if it was possible to do and as someone who is fairly new to all this, I was not going to take any chances, which is why I turned to you good folks. I still have much to learn and this was yet another step in my learning process. Chickenthief, I have started looking into the links and info you forwarded. Thanks, I really appreciate your providing me this. And RCS and JW's expertise was very informative! I don't think there is such a thing as having too much good information.
This is a great sport and this community makes it that much better! Much thanks to you all, and for what it's worth I did put in an "Accuracy" vote for each of you above...
