The cabin crew at the back end are the most junior. It is possible that one of them reported the graunching noise to someone higher up the food chain, only to be squashed for her lack of experience. The 'Cantonese Mafia' in CX can be very snotty. Years ago, when CX boasted ' cabin crew from ten Asian lands,' some of the best Chief Pursers were from India, Japan, Malaysia and Singapore. Their English was impeccable and they actually socialised with pilots and flight engineers. A far cry from the 'Gay Bar' of today.
