I was backpacking in India in 98 and arrived in a small town called Hampi. I was running low on cash so I went I search of an ATM which was not exactly easy in this town I eventually managed to fInd a merchant that charged my card and gave me a wad of rupees that was from memory about $50usd.
I then caught an autorockhaw back to where I was staying. I had been in the room a few minutes when there was a tap tap at the door. There was the
driver who had follewed me in with... my wad of cash, which had fallen out of my pocket somehow. I made sure I used that driver every time i needed a
rickshaw after that , and tipped him accordingly. I was amazed at his honesty. And yes I would do the same thing.
