In June, I had wheelchair assistance in SYD int'l; as a consequence I was taken to the aircraft door, in the chair, before boarding started. One flight attendant peeked out and said, "You can board in a minute." I stood up.
The purser came out with an envelope, and said to me, "I know that all you really want right now is a stiff drink, but I have to inform you that QF is not allowed to serve you alcohol on this flight."
I looked over my shoulder at the wheelchair and said, "Umm, because of the wheelchair???". He looked at the name on my boarding pass, the name on his envelope (which didn't match), shook his head and said, "I'm so sorry. You don't look like the sort of person who gets deported, anyway."
So now ya know - get deported, no get drinks.
