Be Honest

Yesterday, I bought two train tickets for next two weeks from Tainan to Nantou. I ordered them on internet, then wrote down the codes of these tickets and bought them at any train station. Interestingly, in my departed train station, there was just one ticket seller in the ticket window. Perhaps the seller was too busy to count money correctly because there were so many people in train station. He gave me the wrong changes. Theses two tickets cost me 358 NT dollars. I gave him 360 NT dollars so he should give me 2 NT dollars for change. However, he gave me 302 NT dollars. I was astonished and confused why he gave me so much money. I only spent 58 NT dollars for two tickets if I took the changes. I finally return the money because he might be in trouble if he lost 300 NT dollars. I was not regret to return the money, contrarily, I was happy because I was an honest person.
