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.
Yeah, the bag of coins and the upset gals in the tax office are just a side show. I like the fight between the state trying to make a little extra revenue through the sale of vanity plates and the right to free speech. It's a clash going on in all fifty states. I understand there is an office in every state capitol that keeps track of what you cannot have on a vanity plate. I don't have vanity plates just for that reason, and I tell people that if you want to send a message using your vehicle as a bull horn - - buy a bumper sticker.
