you?" The man himself was wearing the distinctive clothing of a Five, so his customers outranked him, but the brassard on his arm showed that his master was a Two, which afforded him enough authority to keep reasonable order in the place. "Where's the nearest Class Three bar?" The Guesser snapped. The barman looked faintly disappointed, but he didn't lose his obsequiousness. "Oh, that's quite a way from here, sir—about the closest would be Mallard's, over on Fourteenth Street and Upper Drive. A mile, at least." The Guesser scowled. He was in the wrong section of town, all right. "But I'd be honored to serve you, sir," the barman hurried on. "Private booth, best of everything, perfect privacy—" The Guesser shook his head quickly. "No. Just tell me how to get to Mallard's." The barman looked at him for a moment, rubbing a fingertip across his chin, then he said: "You're not driving, I suppose, sir? No? Well, then, you can either take the tubeway or walk, sir...." He let the sentence hang, waiting for The Guesser's decision. The Guesser thought rapidly. Tubeways were for Fours and Fives. Threes had groundcars; Ones and Twos had aircars; Sixes and below walked.

The Guesser decided he'd take the tubeway; at the Class Three bar, he might be able to talk someone into driving him to the spaceport later. But five minutes later, he was walking in the direction the bartender had told him to take for finding Mallard's on foot. To get to the tubeway was a four-block walk, and then there would be another long walk after he got off. Hoofing it straight there would be only a matter of five blocks difference, and it would at least spare him the embarrassment of taking the tube. It was a foolish thing to do, perhaps, but once The Guesser had set his mind on something, it took a lot more than a long walk to dissuade him from his purpose. He saw he was not the only spaceman out on the town; one of the Class Five taverns he passed was filled with boisterous singing, and he could see a crowd of men standing around three crewmen who were leading them in a distinctly off-color ballad. The Guesser smiled a little to himself. Let them
