Library Fine

Today i was registering for spring 2008 and noticed there was a red flag on my account. The red flag indicates i cannot register for my classes because of a library fine. I went to the library and asked what book do i owe. Turns out in October 2007 i checked out a book but 45 minutes later i returned the book, but the library said i never returned the book. We had a little dispute and they couldn't find the book. To make the story short i owed the library $33.37 for a $5 book. They are charging me for lamination on the book and handling and restocking fee for a $5 book. RIDICULOUS
