People like to rag on the DMV but to tell the truth, the DMV here in California (at least the offices I’ve been to in the past 40 years) are all pretty efficient and professional. The clients can be a hoot, no question about that, though.
My wife did get upset while getting her ID renewed a while ago because the digital signature device was not working properly at all, and the woman behind the counter would not allow my wife to skip the process. My wife got very upset and I was afraid she’d get kicked out. In the end I encouraged her to just press down with the pen on the malfunctioning device and we left. A couple of weeks later, when she got her ID in the mail she was disgusted to find her signature on it was basically reduced to an illegible squiggle by the malfunctioning DMV digital reader, when in fact her real handwriting and signature are quite clear.
