Whilst being rude and insubordinate to a wheel in public is hardly 'conduct becoming', you may well have valid point with the poo-filtering.
When the TWUs were killed off by the 'mirror image' AFTS training system, it was only when he made a crewroom visit and received a bit of chest-poking that a VSO learned the truth - by which time, of course, it was all too late. "Why wasn't I told this before" was his reported comment.
Similarly, the excellent Waddington sessions with Sir John Allison some years ago were held partly to bypass the multi-level poo-filtering anything raised at squadron shag level had received before it reached his ears.
