Lets face facts.
Cabin crew should stick to slinging the hash, serving the necessary liquid refreshments...and stop thinking they are "in charge". If they want to be constructive, then use the interphone.
Far too many CC have in their brains(?) the thought that they "know" far more then the tech crew about "items technical".
Many I suspect are frustrated in their positions...but they will just have to "get over it". In doing so, they would make everyones duties more enjoyable.
