Just to clarify - I'm not CPL just long expired PPL and I wasn't sure about it being a crack, I just wanted to point out a possible crack. I know I did wrong calling him an idiot in front of other passengers, I had been standing in line waiting to be "processed" for over an hour, and that was after a ten hour flight from NZ. If only he had been a bit more professional (& customer focused) he wouldn't have been called an idiot in the first place! By the way the name calling was fairly quiet, but unfortunately he heard it.
