"Lucky" was a tuk tuk driver who we hired one day to take us to visit Angkor. When we came out of one temple he was purchasing himself a bamboo juice from a trader. When he saw us walking towards him he bought another two straight away as he didn't want to be rude. He refused to let us pay for the extra drinks.
Later in the week he saw us on the road walking into town. He pulled over his tuk tuk and insisted we got in as he was going in our direction anyway. Again he refused to let us pay for the trip. We ended up leaving the money on the seat. When we got back to our hotel later that day, he had left the money at reception for us to collect!-Dan
