My entire career was spent working part time jobs with department permission. The store/function had to get approval from the Chief. Then it was handed down to the LT who posted the assignment list. You had to be in good standing to work one of the available jobs. You showed up in uniform driving your take home car.

In 1986 these jobs were paying $20-$25 an hour cash. It could be directing traffic in front of a shopping center during Christmas rush or being a bouncer at the local club.
