Why are so many people so arrogant and nasty as a result?

I went to the store today and asked a question during checkout and the associate answered with an attitude and snark. She also looked at me when the process even started with a look in her eyes like she despised me. There are so many nasty hateful people out there. It surprises me the amount of them. She was acting like I was disturbing her, as though if I had not been checking out with her and asking a question, she would be at a high fashion elite photoshoot getting her photo taken by Nigel Barker or something. People are so arrogant and deluded. You work at Zara. You are not above me. Its your job to answer easy simple questions about the merchandise and checkout process. Lower your ego and come back down to earthm if you're too good to answer a customer's question then go back to your high fashion photoshoot session. Oh wait you can't because you're exactly where you're supposed to be.

Also another thing I notice is nasty people will treat me with disdain and act like I am bothering them meanwhile 2 seconds later they will have this pleasant demeanor and respectful tone and facial expressions when talking to those who are nasty and arrogant like they are. Birds of a feather flock together.
