A dollar for everytime (when i am welcoming at the door) a pax asked me if there was going to be a movie on this flight, Syd-Mel (approx 1hr sector). No sorry, not enough time ma'am - and then they tell you how disappointed their kids will be now!
Or when your at the door and you get the old "ground staff said to ask you about an upgrade".... my response "oh really... well if you just want to stand aside i'll just get ground staff to come down and organise that for you if thats what they said". Amazing how they quickly take their seat down in 54F!
