I have never been a huge cinephile, but once I started working here, I tried my best to take advantage of the free tickets, the reason I say this is because I went from going to the movies maybe once every three months and then started going once a week at least. The amount of money I started spending at the movies went up exponentially, of course they are paying for me, but since the free tickets don't stack, I felt like I was going to miss out on that free ticket, of course it's all an illusion to try to make the employee give more money back to Regal, but it was pretty nice.
TLDR: If you go to the movies a lot, then this job's perks are great! If not then be careful with the employee discounts, you will probably spend more money at the movies after getting a job there. (Probably is true for any job that offers similar perks)
