 Why was the Space Patrolman surprised that Tolliver referred to Betty as "Miss Koslow"?
It had been built for Ganymede, but not for Jeffers. "Okay I can't fire you legally—as long as you report for work," grumbled Jeffers, by now a shade more ruddy. Tolliver began to have his doubts the next day; which was "Tuesday" by the arbitrary calender constructed to match Ganymede's week-long journey around Jupiter. His contract guaranteed a pilot's rating, but someone had neglected to specify the type of craft to be piloted. On the bulletin board, Tolliver's name stood out beside the number of one of the airtight tractors used between the dome city and the spaceport, or for hauling cross-country to one of the mining domes. He soon found that there was nothing for him to do but hang around the garage in case a spaceship should land. Sometimes there's no reason but them for sending a ship back with a crew instead of in an economy orbit. Under a portable, double-chambered plastic dome blown up outside the ship's airlock, a crewman helped him load two trunks and a collection of bags into the tractor. "Sure," agreed Tolliver thinking, Ohmigod! They found they could send back loaded ships by 'automatic' flight—that is, a long, slow, economical orbit and automatic signalling equipment. Then they're boarded approaching Earth's orbit and landed by pilots who don't have to waste their time making the entire trip." He enlarged upon other dangers to be encountered on the satellite, taking care to impress the newcomer with the daredeviltry of John Tolliver, driver of "missions" across the menacing wastes between dome and port. His charge seemed noticeably subdued, but cleared her throat to request that Tolliver guide her to the office of the manager. "Jeffers," he announced, "this is ... just call her Betty." Mr. Koslow—the president, that is: your father—sent a message about you. The pilot stared at Betty, trying to recall pictures he had seen of the elder Koslow. "Wh-wh-what do you mean, Miss Koslow?" "Daddy gave me the title of tenth vice-president mostly as a joke, when he told me to find out what was wrong with operations on Ganymede. He stared unbelievingly at Betty, and Tolliver thought he muttered something about "just landed." Tolliver, hardly thinking about it, expected the someone to be a secretary, but it turned out to be three members of Jeffers' headquarters staff.
 It was a cover name, not her real name.
 It was a cover name, not her real name.  He realized that she was the boss' daughter.  The Space Patrolman didn’t know her name.  She wasn’t supposed to tell anyone who she was.
