Fruitbat, you are doing a really good job of making yourself look silly.
BA refer to CSDs, CSMs CMs on long-haul and CSDs, CSMs and Pursers on short-haul as the cabin manager. They manage the cabin crew and the service and ultimately report to the captain who is incharge of the aircraft.
Obviously when on board or down-route the Captain is the ultimate manager of the SCCM and the rest of the crew because he is the most senior member on board.
Did you not know that a Manager can also have a Manager!!?
Somehow, knowing that you must be intelligent to do your job, I think you did!
