I worked in a school, and going into work one day, I was the car that the back end of the bus sideswiped, putting quite a dent in the shapely rear wing of my car. The driver appeared not to notice, despite a lot of people shouting and waving (for some reason, people seem to get quite aerated when buses start bashing into things at a school gate with dozens of kids milling around ).
I knew which company operated the school buses, so phoned it in to the transport manager, who said he'd inspect the bus on its return. He called back later - "Is your car black?". Apparently, there was a fair bit of black paint on the rear of the nice cream bus .
I was asked to take the car into the garage, and they offered to do the repair, which I agreed to, and I have to say that they did a bang-up job. I think the wheel arch had already got a small ding, which was gone when I got the car back 24 hours later.
When I expressed my thanks, the TM did mention that they'd spoken to the driver, that he had denied the collision, despite a gazillion witnesses, and...well, he didn't say what had happened, but he clearly regarded the failure to stop as an aggravating factor and said that the driver had been "spoken to". I have a feeling tea and biscuits were not a part of that conversation.
Some while later, talking to someone who worked at the same company, a driver was mentioned who had a bit of a track record of careless incidents and pretending they hadn't happened, and who'd eventually got the push. I have no idea if the prang involving my car had been the final straw.
