I ever heard of such cases too, the guy unwilling to pay the fine and go to court to appeal several times until it accumulated to 10k+ too. Think this inclusive of the admin fee and lawyer.
IMO, the bailer has to have that unwithdrawel amount in bank in order to bail her. If it is just a matter of few hours just to show proof of money in bank, then I feel that there's no reason to state the bail amount.
The money may still be able to withdraw, but the bailer will have to pay the fine in case the person didnt turn up in court.
