Modern elevators are strange and complex entities. The ancient electric winch and “maximum-capacity-eight-persons” jobs bear as much relation to a Sirius Cybernetics Corporation Happy Vertical People Transporter as a packet of mixed nuts does to the entire west wing of the Sirian State Mental Hospital.
This is because they operate on the curios principle of “defocused temporal perception”. In other words they have the capacity to see dimly into the immediate future, which enables the elevator to be on the right floor to pick you up even before you knew you wanted it, thus eliminating all the tedious chatting, relaxing, and making friends that people were previously forced to do whist waiting for elevators.
Not unnaturally, many elevators imbued with intelligence and precognition became terribly frustrated with the mindless business of going up and down, up and down, experimented briefly with the notion of going sideways, as a sort of existential protest, demanded participation in the decision-making process and finally took to squatting in basements sulking.
An impoverished hitch-hiker visiting any planets in the Sirius star system these days can pick up easy money working as a counsellor for neurotic elevators.
At the fifteenth floor the elevator doors opened quickly.
“Fifteenth,” said the elevator, “and remember, I’m only doing this because I like your robot.”
Zaphod and Marvin bundled out of the elevator which instantly snapped its doors shut and dropped as fast as its mechanism would take it.
Zaphod looked around warily. The corridor was deserted and silent and gave no clue as to where Zarniwoop might be found. All the doors that led off the corridor were closed and unmarked.
They were standing close to the bridge which led across from one tower of the building to the other. Through a large window the brilliant sun of Ursa Minor Beta threw blocks of light in which danced small specks of dust. A shadow flitted past momentarily.
“Left in the lurch by a lift,” muttered Zaphod, who was feeling at his least jaunty.
They both stood and looked in both directions.
“You know something?” said Zaphod to Marvin.
“More that you can possibly imagine.”
“I’m dead certain this building shouldn’t be shaking,” Zaphod said.
It was just a light tremor through the soles of his feet – and another one. In the sunbeams the flecks of dust danced more vigorously. Another shadow flitted past.
Zaphod looked at the floor.
“Either,” he said, not very confidently, “they’ve got some vibro system for toning up your muscles while you work, or…”
He walked across to the window and suddenly stumbled because at that moment his Joo Janta 200 Super-Chromatic Peril Sensitive sunglasses had turned utterly black. A large shadow flitted past the window with a sharp buzz.
Zaphod ripped off his sunglasses, and as he did so the building shook with a thunderous roar. He leapt to the window.
“Or,” he said, “this building’s being bombed!”
Another roar cracked through the building.
