I view an airport as a sort of AD&D dungeon, with helpful vehicles that can carry you around instead of monsters. Getting from one useful place to another means moving through long corridors while being careful to take all the correct turns and not get lost. So I had a minor culture shock when I asked a pilot (who was buying coffee) how to get to my gate.
He pointed out a big glass window at a cluster of planes near another building. "That's where your gate is," he said. "To get there you'll need to walk up that way and around."
