There is an old story about a young 8 year-old girl.
The girl entered an ice cream parlour and took a seat in front of the cashier.
The waiter came and put a glass of water in front of her.
“How much is a mixed ice cream cup?” the little girl asked.
“1 dollar and 75 cents” replied the waiter.
The little girl pulled her hand out of purse and studied the coins she had. “Well, how much is a plain ice cream?” she inquired.
By now, more people were waiting for a table and the waiter was growing very impatient. “1 dollar and 50 cents,” he impatiently replied.
The little girl again counted her coins. “I’ll have the plain ice cream,” she said.
The waiter brought the ice cream, put the bill on the table and walked away. The girl finished the ice cream, paid the cashier and left. When the waiter came back, tears came out of his eyes.
As he wiped down the table, there placed neatly beside the empty dish were 25 cents. You see, she couldn’t have the mixed ice cream because she had to have enough money to leave him a tip!!
