This could almost be a follow up to my post about the lack of respect shown by other road users.
On Saturday morning I popped up to our Sainsbury's Local. When leaving I witnessed a woman in a Renault Megane reverse into a black Seat Leon Cupra. The impact left quite a dent in both cars. I sticked around to make sure the woman left a note, and asked her in passing to make sure she did. She said she would but walked right past me and into the shop. Thinking the worst I photographed both cars and went home to grab a piece of paper. Upon returning the Renault had left, but the Seat was still there. She hadn't left a note, so I did, leaving my mobile number in-case they needed it.
A good deed I thought! However, and may be I'm wrong to expect it, the owner of the Seat hasn't contacted me to express any sort of gratitude. I'm still pleased I did it, but in the same situation I'd have been straight on the phone.
