I can't imagine many jobs more stressful than ticket agent at an airport gate. Between people who are justifiably irate, people who are just jerks, and people who are scared to death or dealing with emotional trauma on their way to sick people or dead relatives, plus the inevitable people who are trying to fit a bus worth of carry-on luggage on, and then the responsibility to personally assess the risk that any given passenger might engage in terrorism/giving birth/being a drunken lout/etc. ... bleah!!!
I watched an episode of Air Crash Investigation about the Air India bombing back in the 80s. A Canadian ticketing/check-in agent allowed a man to check a bag through to India when, if I recall correctly, the bag should have been rechecked in the connecting city. The woman knew it was against regulations but the woman and several witnesses testified that the man badgered her so hard that she gave in - something people did all the time back then. She had to live with the fact that a bomb was in that bag and nearly 400 people died. Awful.
Aikiweezie, my intense dislike of O'hara is based on the fact that the terminal that I always end up - (wherever US Air connects though) - has very little vegetarian food options. I always tell myself I'm going to find my way to a better terminal to eat, but never manage to do so. I just end up cranky and hungry. You can't get a vegetarian meal on US Air anymore either. But even I know there has to be a better terminal in the world's largest airport.
