Udurawana rushed back angrily to the grocery shop from where he had purchased a packet of butter a few minutes ago.

"Where is my free gift?" he shouted at the shopkeeper. "But

"Don't fool me," replied udurawana, "it is clearly written
on the packet of the butter 'Cholesterol free' but you gave me only butter".
