Car ticketed while in care of valet parking

What would you do it you were traveling and the valet at the hotel got a parking ticket? Don't snicker, I am asking because of an article at CNN where a valet got a parking ticket with customer's car. And when the traveler finally learned of the ticket, long after they returned home, they have been having a headache of a time trying to get reimbursed for the cost of the parking ticket. She did eventually get a reimbursement for the ticket, but would you know what to do in a similar situation?
