Boy and Ice Cream

When special ice cream (ice cream sundaes) are still cheap, a boy aged about 10 years into the Coffee Shop, and sat at the table.. A waitress approached, and gave the water to him..

This child is then asked "How much the price of one ice cream sundae?"
"50 cents..." replied the waiter..
The child then removing the contents of his pocket and counted and studied the coins in his pocket..
"Well.. How much for the normal ice cream?" he said again..
But this time the people sitting at other tables have started a lot, and the waitress was getting impatient..
"35 cents!!" the waiter said with a grumpy..
This child began count and learn his coins again..
"Miss, if so I ordered just normal ice cream.." he said..

The waitress then brought the ice cream, put a bill paper on the table and continued to walk away.. The child start to eat ice cream, paid the cashier and go away.. When the waitress back to clear that little boy's table, and she began to cry.. Arrayed neatly beside the empty cup, there are 2 pieces of 10 cent coins and 5 pieces of 1 cent coins..

You can see, that little boy could not order ice cream sundae, because it does not have enough to give the waitress a "proper" tip..
