Shortly after high school, I worked at two part time jobs. One was a hospital and the other was a clothing retailer. One day, the regional manager was at the clothing store, and an employee was caught ringing up a sale for her friends. The problem was, this was before price scanners, and the employee was putting in things like $0.57 for a shirt, and there was a whole bunch of stuff. The employee was fired immediately.
A few years later, I was working full time at the hospital. My department worked with HR, and so I got left to man the office when the entire small HR department had some sort of event offsite. My former coworker came in and filled out an application. When the HR people returned, I told them why this woman had been fired when I worked with her before, but they hired her anyway! I never could understand the motivations of the people in that HR department.
