From an official standpoint, I would probably have to say when I got stopped for a non-moving violation and the Trooper looked at my recently renewed license (name was the only change at the time, no court order was used- the new plastic was barely a week old) and pointed out that the clerk had made a mistake. When I questioned what he was saying, he noted that the clerk had put an M on there and that I probably ought to go back to DPS and get them to change it...he said the citation he wrote would be enough to get them to fix it. He was right. That was 20-25 years ago...
