Adjustment Team

"Adjustment Team" is a science fiction short story by American writer Philip K. Dick. It was first published in Orbit Science Fiction (September–October 1954, No. 4) with illustration by Faragasso.
A man called the Clerk approaches a talking dog, and explains in businesslike manner that "Sector T137" is scheduled for "adjustment" at 9 o'clock. He instructs the dog to bark at exactly 8:15, which the Clerk explains will summon "A Friend with a Car", which will take real estate salesman Ed Fletcher to work before 9, but while the Clerk is preoccupied, the dog falls asleep and as a result barks a minute too late. Inside Ed's house, while he is getting ready for work, Ed is accosted by a door-to-door insurance salesman and doesn't leave for work until 9:30. Ed arrives at his office building, but upon stepping onto the curb, finds himself in a sunless version of the world where everything and everyone is immobile, ash-grey, and crumbles at his touch. Ed is accosted by white-robed men, who talk about "de-energizing" him with a hose-like piece of equipment, but he flees outside and across the street, back to the everyday world, fearing he's had a psychotic episode...
