Bonza as I said bad manners are unforgivable, you do have a right to complain and I believe you should do so directly to QF as well.
As far as spelling is concerned, I didn't know that this was a spelling bee!
However you are a little out on your comments on cost. I just had a look at both airlines internet sites and at the end of the day there is not much between the two airlines fares between BNE-MEL. (even though you were at OOL).
You were comparing a Business fare with an Economy fare out of different ports, not exactly apples for apples.
