You've clearly never worked customer support. A very disproportionate number of people who call in to customer support are totally and utterly unreasonable. That's why it's such a pain to interact with customer support as a reasonable human: The systems aren't designed for you, they're designed for the abusers who represent something like 20% of the phone calls and 80% of the work.

Never worked in customer support huh? Sometimes the first thing you ever hear from a person is them cursing at you. Some people don't even greet you and act downright uncivilized, yelling, aggressive, assuming you not magically only know their problem without them telling you, no you also somehow caused it, on purpose, because you're evil. They haven't even given you a passing chance of helping them.

As someone who grew up in the EU I believe that human dignity is an fundamental right, and that treating a person in a support role with basic manners is in the spirit of that right.
