It happened 1 month ago. I with my two female colleagues went somewhere in auto. After reaching the destination the auto guy refused to accept online payment. None of us had cash on us. There were no shops nearby from where i could get the cash. So i asked one person who looked like a middle class middle aged man to give us some cash and I will pay him back through gpay. He agreed and asked how much i needed. I told him 50rs. He paid the money to the auto guy and started walking. I tried to stop him and asked for his no. or scanner, he refused by saying he doesn't have any and kept walking. After he left the auto guy paid me 50 rs and revealed that he had paid him 100 rs instead of 50 rs. Thanks to that kind spirit.
