Douglas Adams said this quote

After a moment or two a man in brown crimplene looked in at us, did not at all like the look of us and asked us if we were transit passengers. We said we were. He shook his head with infinite weariness and told us that if we were transit passengers then we were supposed to be in the other of the two rooms. We were obviously very crazy and stupid not to have realized this. He stayed there slumped against the door jamb, raising his eyebrows pointedly at us until we eventually gathered our gear together and dragged it off down thecorridor to the other room. He watched us go past him shaking his head in wonder and sorrow at the stupid futility of the human condition in general and ours in particular, and then closed the door behind us.The second room was identical to the first. Identical in all respects other than one, which was that it had a hatchway let into one wall. A large vacant-looking girl was leaning through it with her elbows on the counter and her fists jammed up into her cheekbones. She was watching some flies crawling up the wall, not with any great interest because they were not doing anything unexpected, but at least they were doing something. Behind her was a table stacked with biscuits, chocolate bars, cola, and a pot of coffee, and we headed straight towards this like a pack of stoats. Just before we reached it, however, we were suddenly headed off by a man in blue crimplene, who asked us what we thought we were doing in there. We explained that we were transit passengers on our way to Zaire, and he looked at us as if we had completely taken leave of our senses.'Transit passengers? he said. 'It is not allowed for transit passengers to be in here.' He waved us magnificently away from the snack counter, made us pick up all our gear again, and herded us back through the door and away into the first room where, a minute later, the man in the brown crimplene found us again.He looked at us. Slow incomprehension engulfed him, followed by sadness, anger, deep frustration and a sense that the world had been created specifically to cause him vexation. He leaned back against the wall, frowned, closed his eyes and pinched the bridge of his nose.'You are in the wrong room,' he said simply. `You are transit passengers. Please go to the other room.'There is a wonderful calm that comes over you in such situations, particularly when there is a refreshment kiosk involved. We nodded, picked up our gear in a Zen-like manner and made our way back down the corridor to the second room. Here the man in blue crimplene accosted us once more but we patiently explained to him that he could fuck off.
