Once they hit their limit of 10, they can't check out any more. What fats will try to do instead is use their relatives' cards to get even more, or their kids. We can't say no to parents using their kids' cards because they are registered as associated users until the kids turn 18. So, (and this situation has happened before), you have 1 parent checking out 40 DVDs, 10 on her card and 10 on each of her kids. We have to do that, per policy, because she is a registered user for her kids. If you are not on the card as a user, however, we get to deny the checkout. You have to bring items to the desk to check them out, and DVDs are kept in cases behind the desk. So you bring up empty cases to get discs. I, the abused librarian, have to fill those cases. So yeah. Fats trying to abuse the system, what's new?
