Stephen Kings The tommyknockers (1993) - not safe.
There's a few instances in the book,
cops driving downhill, and stopping "let me out I feel sick", and he runs to v* on the side of the road. It's very tv, a few seconds only nad you dont see or hear much.
later when Jim Gardner discovers something in the shed, when he leaves he goes to v* in the kitchen sink, it mostly sounds like coughing and you only see him bent over for a few seconds.
