50 cents, replied the waitress
the little boy pulled his hand out of his pocket and studied a number of coins in it
how much is a dish of plain ice-cream he inquired some people were now waiting for a table and the waitress was a bit impatient
35 cents she said rudely
the little boy again counted the coins i will have the plain ice cream he said the waitress brough the ice cream paid the cashier and departed when the waitress came back she began wiping down the table and then swallowed hard at what she saw
there placed neatly beside the empty dish were 15 cents-her tip
