<passage>:
Keep your nerve, Peter Manners told himself appointment, hadn't eased Peter's nervousness by admitting, "I don't know what in hell he's looking for. He's turned down every man we've sent him." The interview was at three. Fifteen minutes to go. Coming early would betray overeagerness. Peter stood in front of the Lex Industries plant and studied it to kill time. Plain, featureless concrete walls, not large for a manufacturing plant—it took a scant minute to exhaust its sightseeing potential. If he walked around the building, he could, if he ambled, come back to the front entrance just before three. He turned the corner, stopped, frowned, wondering what there was about the building that seemed so puzzling. It could not have been plainer, more ordinary. It was in fact, he only gradually realized, so plain and Something else was wrong. Peter looked for minutes before he found out employees' entrance was on the third side. It wasn't. Staring back at the last blank wall, Peter suddenly remembered the time he had set out to kill. He looked at his watch and gasped. At a run, set to straight-arm the door, he almost fell on his face. The door had opened by itself. He stopped and looked for a photo-electric eye, but a soft voice said through a loudspeaker in the anteroom wall: "Mr. Manners?" "What?" he panted. "Who—?" but the soft voice said: "Follow the open doors down the hall. Mr. Lexington is expecting you." "Thanks," Peter said, and a door at one side of the anteroom swung open for him. before and shutting after him, until only one was left, and the last of his calm was blasted away by a bellow from within. "Don't stand out there like a jackass! Either come in or go away!" Peter found himself leaping obediently toward the doorway. He stopped just short of it, took a deep breath and huffed it out, took another, you're in no shape for an interview—and it's not your fault—this whole setup is geared to unnerve you: the kindergarten kid called in to see the principal. He let another bellow bounce off him as he blew out the second breath, straightened his jacket and tie, and walked in as an engineer applying for a position should. "Sit down," said the man at the desk. "Let's look you over." front of the desk and let himself be inspected. It wasn't comfortable. flowers!—made him feel as if he had walked down a hospital corridor But then Peter came out of his momentary flinch, and there was an age Peter started, opened his mouth to answer, closed it again. He'd been "Not enough to matter," Peter said, stung by the compliment. Peter looked for a hidden trap, found none. "Of course. Isn't everyone?" "How long have you been out of school?" "Only two years. But you knew that from the Association—" "Some," said Peter, stung again, this time not by a compliment. "After Peter blinked. "Sir?" "I worked my way through," said Peter stiffly. Peter considered his answer carefully. Every man the Association had scared to take on an engineer's job, for fear you'd be asked to do It made Peter feel he had been suckered, but he had decided to play "Why'd you leave?" Lexington pursued, unrelenting. "I finished the course and the increase they offered on a permanent basis wasn't enough, so I went elsewhere—" "With your head full of this nonsense about a shortage of engineers." Peter swallowed. "I thought it would be easier to get a job than it has "Well," said Lexington unexpectedly, "there is a shortage! And the "I don't know," Peter said. "All right, you have," Peter said angrily. "And now you're wondering why I don't get somebody fresh out of school. Right?" Peter straightened up and met the old man's challenging gaze. "That and Peter had the startling feeling that Lexington was rooting for him! So suddenly that it was almost like a collapse, the tension went out "At least I can face knowing how much I don't know," said Peter, "if In precis form, Peter listed his observations: the absence of windows at sides and rear, the unusual amount of power, the automatic doors, the lack of employees' entrances. "Very good," said Lexington. "Most people only notice the automatic Peter stared his disbelief. Automated plants were nothing new, but The office door opened, and Peter found himself being led down the disorganized machinery, Peter noticed that the factory lights high overhead followed their progress, turning themselves on in advance They gave Peter the creeps. Simple square boxes, set on casters, with Peter tore his eyes away from them in time to see the look of replaced by one of anger. He said nothing, however, and led Peter to shortages or overages, and store the materials here," he said, the trace of anger not yet gone from his voice. "When an order is received, you through the manufacturing and assembly sections right now, but they're too noisy for me to explain what's going on while we're there." Peter followed numbly as Lexington led him through a maze of machines, something to do. The two-armed manipulators Peter had just seen were exit, but his apprehension was unnecessary. The machines seemed to know where they were and avoided the two men, or stopped to wait for them to go by. asked Peter, trying to shake off the feeling of open amazement that The shock of what he had just seen was showing plainly on Peter's face sagging and pale. Peter didn't trust himself to speak, and let the idiotic notions about specialization." Lexington mopped his forehead with a large white handkerchief. Apparently the walk through the factory had tired him considerably, although it hadn't been strenuous. He leaned back in his chair and began to talk in a low voice completely in contrast with the overbearing manner he had used upon Peter's arrival. "You know what we make, of course." "Yes, sir. Conduit fittings." "What happened to your original company?" Peter asked. assets, but only one employee—me. "I thought everything would be rosy from that point on, but it wasn't. I found that I couldn't keep up with the mail unless I worked "I—I don't understand," stammered Peter. logic circuits were concerned. Its object was to get me to press that button. Every day I'd press it at the same time, unless things weren't going well. If there had been trouble in the shop, I'd press it late, or maybe not at all. If all the orders were out on schedule, or ahead of time, I'd press it ahead of time, or maybe twice in the same day. Pretty soon the machine got the idea. "I'll never forget the day I picked up an incoming order form from one of the western jobbers, and found that the keyboard was locked when I keyboard so I couldn't enter the order twice. I think I held down the kicker button for a full five minutes that day." silently into the room. Stopping in front of Peter, it waited until he Peter looked for the speaker in the side of the cart, saw nothing, and on it. Peter took it and sipped it, as he supposed he was expected to Lexington took the coffee from the top of the car, obviously angry about something. Silently, he waited until the cart had left the Peter looked at his, which was eggshell thin, fluted with carving and Peter searched for a comment, found none that fitted this odd outburst, I hated to waste two hours a day driving to and from my house, and I also wanted to be on hand in case anything should go wrong that the "It sounds pretty awkward," Peter put in. the machine had taken the damnedest risks you ever saw on bids and contracts for supply. It was quoting impossible delivery times on obvious reason. Inexplicably, we always came out on top. It would turn out that on the short-delivery-time quotations, we'd been up against "It sounds wonderful, sir," said Peter, feeling dazzled.
