I agree with all the above.
About 13 years ago I arrived into AKL on 107 and asked the ISM if the crew wanted to meet for lunch? Her reply was "don't bother my crew, they are tired and wont go out"
About 30 mins later the ISM and about 6 crew passed me in the Lobby on the way out for lunch.........................
I've never forgotten that.
However I have had some REALLY good trips to CMB and BAH with our girls lately. Just when you give up being nice they do something you'd never expect.
The key to getting good service on the flight and on the overnight ( he he ) rests with the ISM and how you get along with her.
