<passage>:
Harvey and Joe were the slickest con-men ever to gyp a space-lane sucker. Or so they thought! Angus Johnson knew differently. He charged them five buckos for a glass of water—and got it! they seen anything like the amazing creature in that colonial saloon. Paying no attention to them, it was carrying a case of liquor in two hands, six siphons in two others, and a broom and dustpan in the remaining pair. The bartender, a big man resembling the plumpish Harvey in build, was leaning negligently on the counter, ordering this impossible being to fill the partly-emptied bottles, squeeze fruit juice and sweep the floor, all of which the native did simultaneously. He led the way inside. Through thirst-cracked lips he rasped: "Water—quick!" Without a word, the bartender reached under the counter, brought out two glasses of water. The interplanetary con-men drank noisily, asked for more, until they had drunk eight glasses. Meanwhile, the bartender had taken out eight jiggers and filled them with whiskey. Harvey and Joe were breathing hard from having gulped the water so fast, but they were beginning to revive. They noticed the bartender's impersonal eyes studying them shrewdly. proclaiming this magic medicine the sole panacea in the entire history of therapeutics." "Yeah?" said the bartender disinterestedly, polishing the chaser "Mayor takes care of that," replied the saloon owner. "If you gents're finished at the bar, your drinks'll be forty buckos." Harvey grinned puzzledly. "We didn't take any whiskey." "Might as well. Water's five buckos a glass. Liquor's free with every chaser." Harvey's eyes bulged. Joe gulped. "That—that's robbery!" the lanky man bartender apologetically. "Don't mind my friend. His adrenal glands are sometimes overactive. You were going to say—?" The round face of the barkeeper had assumed an aggrieved expression. thirst." The saloon man removed his dirty apron and came around the bar. "If that's an apology, I accept it. Now the mayor'll discuss filling them. The planetoid man worked the pump while the mayor intently watched the crude level-gauge, crying "Stop!" when it registered the proper amount. Then Johnson rubbed his thumb on his index finger and wetted his lips expectantly. Harvey bravely counted off the bills. He asked: "But what are we to Johnson's response almost floored them. "Who said anything about charging you for battery water? You can have all you want for nothing. It's just the purified stuff that comes so high." back to the saloon. His six-armed assistant followed him inside. "Now do you see, my hot-tempered colleague?" said Harvey as he and Joe picked up buckets that hung on the tank. "Johnson, as I saw instantly, is the victim of a difficult environment, and must charge accordingly." "Just the same," Joe griped, "paying for water isn't something you can "What's this doing here?" Harvey asked, puzzled. "I thought Johnson had have had the best of this colonial con-man! Watch your cues from this point hence." Fists clenched, the two returned to the saloon. But at the door they Johnson's eight-foot son, topped by a massive roof of sun-bleached hair ?" demanded Johnson. "I come down with it every year, and I ain't hankering to have it in an off-season. Get him out of here!" Instead of replying, Harvey hurried outside to the ungainly second-hand rocket ship in the center of the shabby spaceport. He returned within a few minutes, carrying a bottle. put the bottle to his lips and tilted it until he was forced to drink. When Joe tried to pull away, Harvey was inexorable. He made his partner drink until most of the liquid was gone. Then he stepped back and waited for the inevitable result. "For you, since you have taken us in so hospitably, a mere five hundred buckos." Johnson did not actually stagger back, but he gave the impression of doing so. "F-four hundred," he offered. "Not a red cent less than four seventy-five," Harvey said flatly. , an elegant bottle-opener, a superb product of Mercurian handicraftsmanship." Johnson stabbed out a warning finger. "No tricks now. I want a taste of that stuff. You're not switching some worthless junk on me." Harvey took a glass from the bar and poured him a generous sample. The mayor sniffed it, grimaced, then threw it down his gullet. The ensuing minute saw a grim battle between a man and his stomach, a battle which swindled to the tune of ten buckos a liter? Where would our profit have been, then? No I had to use the bitter free water, of course." "But why use it on me?" Joe demanded furiously. Harvey looked reprovingly at his gangling partner. "Did Johnson ask to taste it, or did he not? One must look ahead, Joseph. I had to produce the same that swindler cheated us, besides whatever other funds or valuables he possesses. We could not be content with less." Joe was still dazed by that monetary vista when he and Harvey carried the case of medicine to the saloon. The mayor had already cleared a place of honor in the cluttered back room, where he told them to put it down carefully. Then he took the elaborate bottle-opener Harvey gave him, reverently uncorked a bottle and sampled it. It must have been at least as good as the first he gagged. Harvey and Joe looked at each other. They hadn't been thinking about food at all, but suddenly they realized that they were hungry. "It's only water we were short of," Harvey said apprehensively. "We've chance of company. Genius, the six-armed native, appeared from the dingy kitchen with two menus in one hand, two glasses of water in another, plus napkins, silverware, a pitcher, plates, saucers, cups, and their cocktails, which were on the house. Then he stood by for orders. Harvey and Joe studied the menu critically. The prices were phenomenally low. When they glanced up at Johnson in perplexity, he grinned, bowed and asked: "Everything satisfactory, gents?" "Think of a fast one fast," Joe agreed. "You're right." "But I dislike having to revise my opinion of a man so often," complained Harvey. "I wish Johnson would stay either swindler or honest merchant. This dinner is worth as least twenty buckos, yet I estimate our check at a mere bucko twenty redsents." !" Johnson didn't answer. Neither did Genius he simply put on the table, not a fingerbowl, but a magnifying glass. With one of his thirty ask the sheriff to take over." Johnson, the "sheriff," collected the money, and Johnson, the "restaurateur," pocketed it. Meanwhile, Harvey tipped Joe the sign to remain calm. "I don't get the connection," objected Johnson. "Well, by obliging us to pay such a high price for your dinner, you put carelessness. "Perhaps you wouldn't have accepted it, anyway." "That's right," Johnson came back emphatically. "But what would your offer have been which I would have turned down?" sell." "Oh, come now, Mr. Johnson. Don't tell me no amount of money would tempt you!" "Nope. But how much did you say?"
