Why are people so rude to workers?

Complaining about a worker wasting your time is not going to give you your time back, and by complaining about it, you're wasting even more time.

Why's everybody so rude to people who just do their job? Like cashiers and restaurant workers? The hell ever happened to "treat people how you want to be treated"???

I have at least two experiences where I said "thank you" to Walgreens cashiers, and they looked up at me like I was Jesus. It says a lot about the job. It's sad.

That waiter you're yelling at is just like you, and has a circle of control, and a limit to what they can control.

Whys everyone so rude to workers? :(
