Will the store be held responsible for any of this and what kind of punitive damages could he seek since his vehicle was repaired?

A customer was illegally parked on the road and a pizza delivery driver backed into his vehicle. Drivers carry their own insurance. The pizza shop does not insure drivers. Neither party was cited as they were both found to be at fault. The employee agreed to have his insurance pay for repairs. The customer is now upset that the driver wasn't fired and is threatening to seek punitive damages. He is not in the vehicle when it was backed into.
