I attempted to discuss this with him after the dive, but we were both tired and probably upset with each other...
That's where it's a bit odd. We have our instructor, and then there is a student instructor (just completed their instructor certification) who teaches our class while the main instructor teaches the basic scuba (both were scheduled for same time, scheduling error). The student instructor just kind of chuckled when this was mentioned (student instructor was one out with us on the dives).
Our instructor is really busy, and I'm not sure how to even bring this up with him without it becoming an issue, and I don't want to discuss it with him with the student instructor around (think it might get blown off as "oh, they just got separated on the dive").
Both of us are advanced certified, but are in advanced scuba class, so I'm assuming (I know, dangerous) that we abide by class rules and regs. No one in the class seems to think it was that big a deal (with the following of protocol), and I'm wondering if I'm making a mountain out of a molehill...My head and gut tells me that I'm not. It bothers me to no end that it seems to be just a joke. I'm not looking for someone to get yelled at, I just would like some clarification and understanding that there could have been serious consequences for lack of planning on both our parts and lack of proper response in following protocol.
