I had to laugh when I saw this thread. It reminded me of an occasion about a year ago when, on arriving at the aircraft, we found the passengers all gathered round the boarding gate despite the fact the flight was on time. We had to fight our way through and one, very well to do lady, took particular umbrage at us "pushing in". She insisted that we should wait in the queue as we couldn't go anywhere without her anyway. It was with great pleasure that I explained that, actually, we could go without her, however, she definitely couldn't go without us!
