Add to that staff misquoting ACPs as if they don't expect you to have ever read them and using the misquoted version as gospel.
Recent example, presentation evening at HQ, (Very much a social occasion for cadets and staff and a few parents.) One staff member bought an adult cadet a pint at the bar. He then walks into the next room and is rinsed by two other staff members for drinking alcohol. He points out that he was bought it by a member of staff, but that didn't dissuade them one bit. It was the cadet's fault. They said to him "Cadets don't drink alcohol in uniform. It's the most black and white rule in the book."
Well, except that it isn't:
Personally, if I had been told by a cadet he had been bought it by another member of staff, I would have checked out the story, then had words with the member of staff, (if I cared) not embarass the cadet in front of a room of his friends. (Who all sided with him obviously and lost what respect they may have had for the two members of staff.)
