That service you got was a domestic Business Class. It is not comparable to the service on an international flight. Just cause its a 744 does not mean a thing these days. Its just a 737 on steroids really. Having said that I have never had a hot meal put on my tray in Business Class with the foil still on it.
Rather sadly the nice things in life here in Oz seem to be going the way of flying in the United States. No more table cloths in Business on short hops etc. CNS to SYD is
a relatively short flight so it seems it falls under these new conditions.
