In the days when an ice cream sundae cost much less, a 10-year-old boy entered a hotel coffee shop and sat at a table. A server put a glass of water in front of him. “How much is an ice cream sundae?” he asked. “Fifty cents,” replied the server. The little boy pulled his hand out of his pocket and studied the coins in it. “Well, how much is a plain dish of ice cream?” he inquired. By now, more people were waiting for a table and the server was growing impatient. “Thirty-five cents,” she brusquely replied. The little boy again counted his coins. “I’ll have the plain ice cream,” he said. The server brought the ice cream, put the bill on the table and walked away. The boy finished the ice cream, paid the cashier and left. When the server came back, she began to cry as she wiped down the table. There, placed neatly beside the empty dish, were two nickels and five pennies. You see, he could not have the sundae, because he had to have enough left to leave her a tip.
