question:  Despite the menu prices for the restaurant food being remarkably low, how were Harvey and Joe met with an outrageous bill of 328 buckos?
context: When Harvey staggered pontifically into the battered metalloy saloon—the only one on Planetoid 42—his tall, gangling partner was already stumbling out, mouthing something incoherent. 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 interplanetary con-men drank noisily, asked for more, until they had drunk eight glasses. Our condenser broke down, and we've gone without water for five ghastly days." Water's five buckos a glass. "Friend," said Harvey, taking out a wallet and counting off eight five-bucko bills, "here is your money. "And chief of police, no doubt," said Harvey jocosely. "About seventy-five liters, if we go on half rations," he answered. "On account of the quantity, I'm able to quote a bargain price. Shucks, boys, it hurts me more to charge for water than it does for you to pay. The planetoid man worked the pump while the mayor intently watched the crude level-gauge, crying "Stop!" when it registered the proper amount. Ten buckos a liter would be preposterous. "Now do you see, my hot-tempered colleague?" said Harvey as he and Joe picked up buckets that hung on the tank. "Just the same," Joe griped, "paying for water isn't something you can get used to in ten minutes." It was on the sixth trip that Joe caught a glimpse of Jupiter-shine on a bright surface off to the left. The figure, 750, with the bucko sign in front of it, was still doing acrobatics inside his skull and keeping a faint suspicion alive in him. Harvey studied it worriedly, put his own hand somewhere on it, swallowed as it closed, then breathed again when his fingers were released in five units instead of a single compressed one.
