About 15 years ago a fellow sued the Virginia Secretary of State when the State revoked his "GOVT SUX" license plates.
During the trial it was revealed that he had tried to pay his Personal Property Tax bill in person with a bag of change. It was also revealed that the two gals in the Loudoun County Tax Office had personally complained to the Secretary of State about the license plates.
He won the case and was able to keep his plates.
I enjoy looking at this kind of thing from theory, not agitating employees or anything like that. Heck, most of them are secretary/clerical types who have worked there 40 years and stuff, real troopers and I bet it's a bad idea to tick them off.
