Pros
Great co-workers, free movies, 1/2 off concessions, easy work/pretty simple to learn, good first job/it's a good place to start and learn the basics (like being a cashier/working with money, learning to work with customers face to face, etc.)
Cons
The pay sucks, but that's just how that is. Really strange hours--sometimes I would have a shift that was 4 pm - 1 am, then the next day I would have a shift that was 8 am - 5 pm. It's not hard work but it can be kind of gross because everything is sticky from soda or Icees or whatever. You have to have a doctor's note whenever you call in sick, which can be a pain (and can be expensive). In my experience with management, they are much more inclined to believe you are just skipping work (and not that you're actually sick). Also in my experience, the managers will flag you for tiny reasons, so be careful (can you tell I'm a little bitter about one specific experience? It didn't just happen to me though! They flag you for some small reason then they don't give you a reason to explain yourself! This may just be at my cinemark, though). This makes it sound like I hated working at Cinemark, but I actually did like it. It was pretty fun.
