Can't say I've been in many offices, but unless OSHA mandates toilets for your paperwork prison, I'm going to say no.

[This is a joke.]

If I had to make a guess, I'd say cult shit. They made that makeshift church-looking building in another office place. It really seemed like the town was divided up at some point, you know? All this graffiti and whatever didn't show up so much until people got east, and there's that rubble in the middle of the museum that people had to dig through before anyone could get to the other side.
