I loved the story about the Argentinian taxi driver Santiago Gori who found a bag of cash worth over £20,000 in his cab and returned it to its owners. 

People in Argentina have been so delighted by Santiago Gori's honesty that they've donated thousands of dollars to him through a website honouring him.

Taxi drivers are obviously an honest breed, as I had a similar – but less dramatic – experience last year. I arranged a cab home from a local railway station through Rely-On Car Hire in Gerrards Cross, Buckinghamshire. The next evening, I was surprised to find the cab driver at my front door. "You overpaid me last night – here's the extra £10 change!" I was amazed and delighted. Needless to say, they've got a customer for life now!
