I only worked this job to help pay for my textbooks and basic food needs while on campus. However, they would give me almost no hours and made me work every weekend from either 12am-4am or 4am-8am. These were shifts that were supposed to be rotated every time and we were supposed to have every other weekend off so we could go home and see family. That almost never happened and I had to ask a couple of months ahead of time to even have a hope of getting it off.
The job itself was very boring, as not many people came in at these hours and most would be drunk, which I was not allowed to report unless they were unable to swipe their card.
This did give time to work on homework, but it's hard to be productive that late at night
