Exactly. Same thing for court time. A cop delivers a piece of paper or comes by to check on status of their case and it takes them 5 minutes. Boom 4 hours. That's what they've bargained for, so they get it.
Yup, I knew a cop in the late 80s that was a few years from mandatory retirement. He would work nights so any court time was OT and was given multiple short details that paid 4 hours, all to pump up his pension (based on his last years earnings). Funny, I can't remember his name but I remember where he used to park for his late night naps.
