Many complaints online from reasonable posters about a culture of declining service (and food.)
Declining food ? Maybe (I would have said declined ).
Declining service - on board - definitely not. QF cabin crew have been delightfully consistent - in their inconsistency - for many years. I don’t think anyone on AFF would be surprised at encountering a QF cabin crew member with such an attitude - but nor would they have been surprised 15-20 years ago either.
