The Grinder

Anyone on the receiving end of the Juvenile Delinquent Education Facility in Johannesburg called it the Grinder. The education given there was two-fold: learn your books and learn to never come back. Six hours a day spent in class. Six hours a day of manual labor.
As the son of a territorial prosecutor, Sammy knew the theory behind facilities like the Grinder: make prisons miserable, show the prisoners a better way while they serve time, and allow them a chance to reform. According to his dad, the system worked.
Sammy never thought he'd actually experience the Grinder for himself.
