I'd be more shocked if I hadn't seen basically the exact same thing happen when I was PersO. Admin yeomanized all the evals, AO and I did final tweaks . . . and then our incompetent CMC insisted on shitting all over everything with his 8th grade grammar before sending it VFR direct to the XO.As the Admin O, the CMC came to me and told me that there were some changes and I should update the Evals. I just kind of paused for a moment, as this was a typical situation of the E-9 tasking the O-4, and mind you as DHs, we've already made our final chop.
Needless to say, that happened once before my boss basically went to war about it. End result was that nothing went to the head shed without the AO being the final chop. Later, we got a CMC that was actually worth something.
