Sucks to deal with these people. I find these abusive customers will use anything to get an employee fired all because "the customer is always right" bs and think they have a right to be abusive. You have a right to be upset over policies or whatever even if the customer doesn't agree with it the problem is they are taking out their anger on the wrong person all the time.

I work in a college I get talked to like I am stupid by students it happens every semester that one student ****s it up all the time. Don't like how the school operates and does things etc not my prob I don't run the school.
