"This is not a self-setting rivet," said Simpkins. "This is a real rivet-set system. Wait, I'll show you one."
Simpkins snapped on the inter-communicator. "Ben? Look, Ben, we've got a new man from I.I.I. here who doesn't know the ropes. Can you bring up a blindy?"
"Sure, but it will be dangerous."
"I'll have the signs posted."
"O.K.," answered Ben. "I'll be up in a minute."
"Look, have you got one that is about to reform?"
"I would get that kind anyway. No sense in tying up the corridor."
"O.K."
It was about a minute later, no more, when a knock came at the door. Simpkins called for the knocker to enter. The door opened and a man in overalls stuck his head in. There was a grin on his face and a smudge of grease on his nose. "Can't, Joe," he said. "You didn't leave the door open."
