That's actually a high school classroom.
The high school the town over was originally built to be a penitentiary but then funding got cut and they stopped the project halfway through, then several years later it was finished as a high school!
It's a huge school, with several cellblocks, er., hallways with classrooms, lined up along one main part of the building.
It's government work! Lowest bidder. Wouldn't surprise me if schools were all meant to be built like prisons. Cheap construction, cheap HVAC, sturdy, etc.
Yeah, the normal IT guy weighs about 130 pounds and has a pencil neck...
