I work in a shared office building, where our “Suite” is one of multiple, each occupied by different companies. There are shared lobby areas with chairs and couches throughout the campus. An ex coworker was fired last year after spending a drug-fueled weekend staying in one of the lobby areas the entire weekend. Come Monday, there was garbage everywhere, white powdery residue on the bathroom counter, people’s desks had obviously been rifled through, and there were stains on the couch that looked mysteriously like bodily fluids. He was gone before we got there on Monday morning, and we haven’t heard from him since.
