Working in the customer service industry, you are expected to show a certain amount of respect.  If you are intolerant of others, perhaps you should pursue another field of work.  Your customers don't deserve disrespect and disdain.  They are paying your salary.  You are there to provide a service. If eldery people annoy you, don't work in a retirement home.  If you hate children, don't get a job at a toy store.  If you think movies are a colossal waste of time, targeted to fat idiots who like candy and butter laden popcorn- DON'T WORK AT A THEATER.  Seriously, there are other options.  But treating the people that you deal with in a rude manner because you hate the joke that is your life, doesn't make anything better.  It just makes you an asshole.
