I've also had someone wo was a Sqn OC shout at me as a CI in a hangar in front of Cadets and other staff because my OC requested changes to a pick up route for the bus for an activity and there were problems as a result, as if it was all my fault that WG HQ messed up - I quickly defaulted back into an Ex-SNCO with 23 years in the real air force and put them back in their box where they stood
Was it one of those very low voiced one sided conversations with just a hint of menace, that senior NCOs ex or otherwise can deliver in spades to officers, in particular those who overstep the mark.
