On the subject of code words. There may be times when they are appropriate but they carry the risk of significant misunderstanding. In a time of relative stress the pilot must ensure they've used the correct code word and the flight attendant must decode it correctly. There's a reasonable chance that something's going to go wrong along the way. Sometimes it might be better to just say "cabin manager to the flight deck now please" with the word "now" denoting the immediacy of the situation (if not already obvious.)
