There's a place for every man and a man for every place, but on robot-harried Mars the Harper's hands twitched violently. "Don't mention that fiasco!" he were the complete antithesis of Harper's picked-crow physique and acknowledged. "Combine a rest-cure with business, eh?" Raising the magazine, he began reading the advertisement. And that was when he saw the line about the robots. "—the only hotel staffed entirely with robot servants—" "Robots!" he shrilled. "You mean they've developed the things to that point? Why hasn't somebody told me? I'll have Jackson's hide! I'll disfranchise him! I'll—" dozen arches. But most of all, the robots won his delighted approval. he watched the robots moving efficiently about, pushing patients in wheelchairs, carrying trays, guiding newcomers, performing janitorial duties tirelessly, promptly, and best of all, silently. Harper was enthralled. He'd staff his offices with them. Hang the proneness to error that was always deviling the most carefully trained office staffs! He'd investigate and find out the exact potentialities of these robots while here, and then go home and introduce them into the field of business. He'd show them whether he was slipping! Briskly he went over to the desk. robot. Harper watched him shrinking and turning pale lavender in the stress of the argument. one! I won't have another of those damnable robots in my room, do you No one within the confines of the huge lobby could have helped hearing. The clerk flinched visibly. "Now, Mrs. Jacobsen," he soothed. "You know the hotel is staffed entirely with robots. They're much more expensive, really, than human employees, but so much more efficient, you know. Admit it, they give excellent service, don't they, now?" Toothily he smiled at the enraged woman. Harper smirked. "My good woman, I'm not a robot. Robots, of course, Harper one of the leading business executives of the earth. Harper's silent and efficient robot. Harper opened his eyes. Two robots were bending over him. He saw that the opening framed the large untidy man who had noisily pounded on the desk demanding service while he, Harp, was being registered. "Say, pardner," he said hoarsely, "you haven't seen any of them robots around here, have you?" Harper scowled. "Oh, haven't I?" he grated. "Robots! Do you know what "Why didn't you stop 'em?" reasonably asked the visitor. "Stop a robot?" Harper glared pityingly. "How? You can't reason with try it!" He ground his teeth together in futile rage. "And to think I had the insane notion that robots were the last word! Why, I was ready to staff my offices with the things!" mentionin'. Temperature always freezin' or below. Pressure suits. Huts. Factory. Processed food. Nothin' else. Just nothin'. That's where they could use some robots. It sure ain't no job for a real live man. And in fact, there ain't many men left there. If old man Hagerty only knew it, he's about out of business." robot enter, wheeling a chair. "A wheel chair!" squeaked the victim. "I tell you, there's nothing wrong with me! Take it away! I'm only here for a rest-cure! Believe me! Take it away!" The robots ignored him. For the first time in his spectacular and The robots not only ignored Harper. They paid no attention at all to Jake Ellis, who was plucking at their metallic arms pleading, "Take me, boys. I need the treatment bad, whatever it is. I need all the There was something nagging at Harper's mind. Something he should do. Something that concerned robots. But he was too exhausted to think it out. For five days now his pet robots had put him through an ordeal that made him flinch every time he thought about it. Which wasn't often, Jake, looking over Harper's skimpy frame, grunted doubtfully. "Maybe Harper looked at his watch. "Time to go. Relax, old man. The robots Harper had guessed right. Gleefully from the doorway of his new room he watched the robots wheel away his equally delighted neighbor for his first treatment. Then he closed the door and began to don Jake's robot operator. Hopefully he stepped out into the hall and shuffled to the elevator. Only the robots were immune to Harper Breen's progress across the huge elevator, he had laid a course for the desk which loomed like an island in a moss-gray lake, and now he strode manfully toward it, ignoring the oversize trousers slapping around his stocking feet. Only the robots at the robots. Things like inkwells and typewriters and card indexes. Especially, card indexes. "Stop it!" begged the clerk. "You'll wreck the system! We'll never get With one last appalled glare at the madman, the clerk picked up an electric finger and pointed it at the approaching robots. They became oddly inanimate. "That's better!" Harper straightened up and meticulously smoothed the Brushing aside the startled secretary in the outer cubicle, Harper My robots!" he muttered. "As if I invented the damned things!" Despondently he looked at Harper. "Go ahead and sue, Mr. Breen. If you resignation." Again he sighed. "The trouble," he explained, "is that those fool robots are completely logical, and people aren't. There's no way to mix the two. It's dynamite. Maybe people can gradually learn to live with robots, but they haven't yet. Only we had to find it out the hard way. We—" he grimaced disgustedly—"had to pioneer in the use of robots. And it cost us so much that we can't afford to reconvert to human help. So—Operation Robot is about to bankrupt the syndicate." aren't you?" Meticulously Harper clipped and lit his cigar. "It seems to me that these robots might be useful in quite another capacity. I might even reasonable price, of course—and forget the outrages I've suffered at your establishment." Hayes leaned toward him incredulous. "You mean you want these robots after what you've seen and experienced?" willing to discuss the matter with your superiors."

Why, the dried-up little turnip was human after all. "All right! Yes, sir! But aren't you going to use some of those robots for office help? Aren't they efficient and all that?"
