Unfortunatly passengers fail to display any the second they walk into an airport.
Ferdnando, your comment is not only arrogant and rude, but is also inaccurate.
Answer me why passengers get confused when the airport infrastructure often provides confusing mixed messages, for example at STN, when the FIDS in the main terminal and the piers don't provide the same status information, e.g. "final call" in the main area and "wait at gate" in the terminal, when the inbound aircraft has not even arrived.
I did confront the BAA duty manager about this on one occasion (of many) and she confronted the airline gate staff whereupon there was an argument and finger pointing about who was to blame for totally confusing a whole bunch of people, many of whom were running down the domestic pier as they were concerned about missing their flight.
And you criticise passengers for being confused
