Stop in for a cup of coffee

So a customer is travelling down highway, woman backs out of long driveway and hits my customers vehicle. Hit hard enough to spin it around.
911 called,ambulance attends and customer goes to hospital to get checked out. Other driver doesent want police involved.
Customer is ok,maybe whiplash but minor.
Next day cop is on customers doorstep handing her a ticket.
Always call the police no matter what for this exact reason
