Why is there a hospital that recommends a reservation deposit even though it is 100% refundable? I said I was looking for another hospital, but they said I would
 have to pay the reservation fee without specifying a date, and they said a 100% refund.. What's the reason? I went without thinking, but when I look at the contract now, it says refund minus the fee, but I don't think it's in the hospital's interest even if the fee is deducted.
