 Why was the Space Patrolman surprised that Tolliver referred to Betty as "Miss Koslow"?
The big moon-face of Jeffers, manager of the Ganymedan branch of Koslow Spaceways, glowered back at him. 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."
 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.
