Maybe You Get Bad Customer Service Because You're a Bad Customer, by Matt Walsh (Huffington Post)

 ... Now, I replay this back to you because I realize you probably scream profanities at minimum wage customer service representatives every time you run an errand or grab a bite to eat, so you might not recall the specifics of this one incident. And that brings us to the possible answer to that query you posed in the midst of your ketchup rant. You asked: "Why can't I ever f*cking get good customer service?" Well, ma'am, that might have something to do with you being a vulgar, miserable, malicious person. Maybe you get bad customer service because you're a bad customer. Did you ever consider that possibility?

I get it. "You're the customer so you're always right." They work here so they have to bend over backwards for you "because that's their job." Well, you're partially correct about that. Yes, you are a customer and, yes, they do work here. But it's actually not their job to deal with psychopaths. They aren't hostage negotiators, they're fast food workers. And even if the powers that be at these corporate chains push this "customer is always right" crap because they've decided it's good business to placate horrible jerks, in the real world, outside the land of plastic chairs and soda fountains, adults who throw temper tantrums in public are never right about anything.
