Used to work for a theme park. We would have shift rotations, and could freely choose when we would clock out for a regular one time 30 minute unpaid break, or just wait until the next rotation and take a quick 15 minute paid break. Since there were 5-6 people in a rotation, you could easily turn a 15 minute paid break to a 30 minute paid break and no one would notice since other workers might be slow, using the bathroom, getting water in between, or being called by management for attendance points. I accumulated a couple thousand dollars doing this before I left the company. No one ever caught on since I was labeled as the goody non rule breaker type of person since I was never late and always clocked in after my actual 30 minute non paid break on the dot. Was a bit weary and paranoid of people that had watches and in my shift rotation though
