Hospitals often have a no-refund policy and so getting charged more than the initial estimate would mean that the hospital overcharged the patient and hence they should not be pleased about it.
Consider the statement "I had to go to the hospital last month and I was charged 400 dollars more than they said it would be.". Based on this "I was really pleased when I found out that the hospital charged me 400 dollars more than their initial estimate" a true statement? Yes, no, or I don't know?
