The law requires parties to exchange information and contact your insurance companies, at a minimum.
If both parties declined to do so, he won't have to worry about any criminal issues.
Is the manager trying to settle this person to person? If that is the case, the only thing I can see is a civil issue if the manager is not satisfied with the payments. It would seem fishy to me. I would not put it past the manager to pocket the cash and tell the owner of the diner it was a hit and run.
I do agree with what RedFord150 said in regards to taking photos, getting the manager's name, and having a paper trail. At least you will be protecting yourself in case the manager pisses backwards.
