3. -Third Important Lesson -
Always remember those who serve.

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 waitress put a glass of
water in front of him. "How much is an ice cream sundae?" he asked.
"Fifty cents," replied the waitress. 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 waitress 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 waitress 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 waitress 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 couldn't have the sundae, because he had to have enough left to leave her a tip.
