A very famous millionaire took a taxi in the city to his house. He paid the driver the exact fare for the ride without leaving any tips.
Surprised, the taxi driver said to the millionaire: “I gave the same ride to your son yesterday, and he left me a hundred dollar tip. So the millionaire replied: “he’s the son of a millionaire, but I am an orphan”.
Moral of this story: The person who struggles to earn his money knows its value.
