That’s how I try to be as well, but when you get flight delays or a connecting flight that got changed to one with a miniscule layover, you sometimes just can’t afford to be patient.
Which sucks, because you know 95% of the people standing up don’t have a real time limit, and so you stand there staring at the back of the person who just wants to be the first to go wait an hour for their flight while you brace yourself for flat out running across the airport.
