a few years back, on the travellator in SIN having just arrived, with a truly loveable BNE s/h CSM.
In the other direction, slouching on the travellator rail, ipod plugged in and audible from 3m away, chewing gum, jacket unbuttoned, hair a mess, was a crew member who was to take our aircraft, her CSM about 10secs behind her who could care less when the issue was mentioned.
Will never forget it.
That said, have flown SQ many times, and find (really!) that the only passengers that rave about them are usually perverts or bogans.
Don't lose sight of the reason passengers love Qantas - rarely will you find crew more down to earth and genuine - you know if they having a bad day or a good day, but generally they are good humoured, direct, relaxed, open books. Sure that means every now and then theres a whinge or a moan, or a bottle of bubbly snuck over to a pax in a Duty Free bag as a modest way of saying 'congrats', 'good luck', 'thanks for the chat' or even 'room 4123'... QF has never been robotic, it hopefully never will be.
One day I hope your managers will realise that their best asset is you, and the fact you are human, and even with a good humoured grumble are able to engage your customer to a much greater degree than any SQ fembot.
