In Illinois going to the DMV used to be much like you described, everyone was short tempered and rude. Today they go out of their way to be pleasant and respectful, nothing wrong with that.
Also in Illinois provided you have had no tickets you can renew by mail. This last January I wanted to get the upgraded to a Real ID on my license. I had to show up in person, bring my passport, SS card, birth certificate and current utility bills. The whole thing took an hour, but I think some of it was because the backlog of being closed for months due to COVID.
