Just because you can't bear what happened to you as a CONSEQUENCE of your behavior DOESN'T GIVE YOU THE RIGHT to behave badly anywhere else.

You should have been focusing on changing your own behaviors & not on jealousy of the fast food coworkers. None of then acted with behavior that created a situation like yours. Look at how they behave verses you & you will KNOW the difference. They are not people to be jealous of but people to learn from how proper behavior in a peofessional setting is to be.
