I just went over to the cafeteria to get some snack from Dunkin Donuts. A strawberry filled donut and a pineapple filled donut, together worth twenty pesos. I gave a 50-peso bill to pay for the donuts, and the lady gave me two 20s and a 10 as change. I took three steps away before realizing her mistake, and then in a knee-jerk reaction I turned back and returned the extra 20-peso bill. I heard the lady make a positive comment about honesty as I left.
Hey, there is still goodness in humanity's instincts! Or at least, in mine. :->
