I am stupidly honest. At the store when the person counting the change screws up, it is hard to get good help, I always say something. They always take it poorly, like they are trying to cheat me, but the mistake is almost always in my favor, and I have to insist that they give me the correct change. Not too much.
When I was little I was selling christmas wreaths in town. I went into a bar to sell one and found a $20 on the way out. I went back into the bar and gave the money to the bartender who promised that he would try to find the owner and if no one claimed it, he would give it to me.
Of course he was thinking found money. If the owner didn't claim it, he would cheat the little kid. I engaged in a game of going in to check to see if it had been claimed every few weeks, he told me not yet, maybe wait another few weeks. I had told my father when I found it. After several months, like the next spring, I got my father to go into the bar to see what was going on with the twenty. The bartender coughed it up and I got it.
Of course it works in reverse. A few friends and I were riding our motorbikes on the autobahn in Germany when we stopped at a rest stop. Sat on the grass and relaxed. Then got on our bikes and sped down the highway. Some distance down the road, miles, one of the guys realized that he left his expensive camera SLR on the grass. We had to travel a while to find an exit and then an entrance, travel past the rest stop until we could turn again and finally got to the grassy area. The camera was gone. But now it gets interesting. Some unknown German had found tne camera, and turned it into the manager of the rest stop, the rest stop had a gas station, restaurant, etc. Then an american army convoy cam through and the manager figured it must have been an american who lost the camera, so he gave it to an officer in the convoy. There were 65,000 us troops in Germany at the time. Why this seemed like a good idea I don't know.
But we sped on up he road until we caught up with the convoy. As we got next to every vehicle we point to our cameras. Up near the head of the convoy, an officer held the camera out the window of the jeep. Our guy reached out and got the thing without stopping. We went on our way to Munich Oktoberfest. Faith in humanity restored.
