Post Office: A Novel by Charles Bukowski:
You had to keep one foot on the floor at all times. One notch up on the restbar. What they called a “restbar” was a little round cushion set up on a stilt. No talking allowed. Two 10 minute breaks in eight hours. They wrote down the time when you left and the time when you came back. If you stayed 12 or 13 minutes, you heard about it.
But the pay was better than at the art store. And, I thought, I might get used to it. I never got used to it.
