Pros
Free movies at any AMC Theater as long as you have your home theater call in for you. Management will easily transfer you to another theater if you request it.
Cons
I worked at a flagship AMC with 20 registers lined up in a row and was cross-trained as an usher, cleaner, and was primarily working concession. Whenever an ICEE machine broke down, no one did anything to help the case because there were more machines, even if that meant having to run from the first register to the 20th for just one customer. No career advancement opportunities whatsoever unless you've been working there for many years. At my branch, breaks were not allowed, even after working 8 consecutive hours (unless you're a minor). You seldom work the hours you are appointed, usually end up working more hours each day.
