Fees imposed by county jails vary - but a majority of them charge nothing at all. It could be that he needs to pay a fee, $65 sounds a little high but it's possible. What it could also be is that he wants money for his commissary so that he may shop to buy certain snacks and food stuffs. Either way, it's probably not nefarious and adding a small amount of money on a weekly basis will allow them to get a few things not provided by the jail.
