Found a wallet last week in the middle of the road. Had a driving license in - checked out how far using google maps and it was a fair distance. I was nearly home so got back and jumped in the car. Drove to the guy's house and his dad opened the door. I explained that I'd found the wallet whilst out cycling and that I'd wanted to return it.
Not a snifter of a 'thank you' - just took the wallet and said that his son must have lost it while cycling as he closed the door in my face
Now I didn't expect tea and cakes but a simple 'thank you' would have been more than enough!
