When I was about to exit the MRT, I saw an old woman pleading to the guard to let her out because her ticket was lost during the train ride. The guards won't allow her to do so unless she pays the lost ticket fee. The old woman insisted that she has no money left. I approached them and I told to the guard that I'll be the one to buy the exit ticket for her. The old woman thanked me as well as the guard on the MRT.
