About 10 years ago, I was working as a waiter. Our restaurant offered a set lunch, and some old man came in, asked the price, sighed, and was about to leave.
I felt sorry for him, so I fed him and paid for the lunch myself.The manager scolded me, saying that they would never stop coming now, but what was done couldn’t be undone.
And in the evening, an ordinary-looking guy left me a very big amount for a tip. At that time I needed money very badly to pay off my rent and my debt. And this amount was enough for everything.
