Read a good story after a long time

Sometime ago, when the ice-creams were not so expensive, a ten-year old boy went to an ice-cream parlour. While sitting at the table, he asked the waitress,
“How much does a Sundae cost?” “50 cents,” she replied.

The boy took out his money from the pocket and began counting it.

...............

"Well, how much does a simple ice-cream cost?".

There were other people waiting to be served, so the waitress began to get a little impatient.

"35 cents!" she replied abruptly. The boy counted his money again and said: “Please get me a simple ice-cream!"

The waitress served him the ice-cream and his bill. The boy ate his ice-cream, paid his bill at the cash counter and left.

When the waitress went to clean the table she began to cry… for there, in the corner of the plate, were 15 cents… her tip.

The boy took a simple ice-cream instead of a Sundae so he could leave a tip for her.
