After a class today, I went to a ETH building (CHN) where there are three floors with several positions where we can study. When I went there, there were 10 CHF on a table. There were some people on this table.
Time went by and, at some point, those who were sitting there had gone and some other people were in their places. The 10 francs still there. I was studying with a friend. Jokingly, we decided to leave an extra of 10 cents on top of the ten francs, just as the prize of the owner who had forgotten the money there (payoff for taking the risk!).
We went for lunch. Now, after 5 hours and several people have passed by, the money are still there! I wonder when the person who has forgotten them is going to drop by..!
I admire this mentality!
