I've been to multiple MVCs/DMVs over my life and generally, the people are fine. They're not bubbling over with high energy like a retail store to get you to buy something.

They're a government agency. And these offices are dealing with hundreds and thousands of people daily who have something that needs personalized and specific attention. Their life is disrupted and they need it fixed.

So massive amounts of grumpy customers, (understandably), with representatives being asked the same 5 questions by almost everyone, and having to verbally repeat the information which is written on the forms in front of them.

Stop being annoyed that these folks aren't thrilled to see you.
