Stopped at a red light (on my way to of an interview - why do these things happen on days like this?) & the car behind me didn't quite stop in time. There are a couple of lines on my bumper but nothing else & his car seemed ok to. I got his business card & asked the car next to us if he had actually seem anything but he hadn't so no witnesses (not that it matters given the lack of damage). Is there anything else I should have done? Just wondering for the next time this might happen so I know what to do. In this case I think I was a bit lucky that nothing needs to go through the insurance companies etc.
