Pros
Free movies, everyone here is so friendly so the work environment is a fun and enjoyable place to work at, and gives you work experience. The management is very understanding when it comes to school/other job commitments. They even can give you two weeks off if you have midterms to study for. I don't know any other job that lets you have this many days off work. Everyone gets along so well which gives you a sense of pride working there.
Cons
Sometimes when the theater is busy, staff can be short-handed making it harder and more difficult to get things done in quickly. Low pay for the work you do, the raises are like 5 cent raises and it's very hard to move up unless you have been working there for 5+ years. Only the upper management can get full-time positions. It's rare where they let you have weekends off so you have no social life.
