These days, kids are pretty much rotten little wankers. Where I work, the wee gits come in and steal the labels off my tools. They think they'll get into less trouble than if they steal the actual tools, but they still have something to show their nasty little friends. "Whoa dood, look what I stole!"
I'd keep a lookout for someone riding around the local brat hangouts with your seat, they are too stupid to hide it.
