As soon as Tim got his pocket money, he jumped on his bike and raced straight down to the shop. “How can I help you?” asked the shopkeeper.

Tim looked long and hard at all the ice-blocks and finally said, “I'd like a lemonade ice-block please”. “Here's your ice-block”. “That will be one dollar and fifty cents”, said the shopkeeper. Tim put his money on the counter and headed out the door calling, “Thanks very much”, as he went.

“Come back”, called the shopkeeper. “There's fifty cents change”.

“In that case”, said Tim, walking back to the counter, “I'll have a packet of chewing gum as well”. “There you are”. “I hope you enjoy it”, said the shopkeeper. “I will”, said Tim.
