My friend Shuba works in a post office and she sells stamps. One day a man walked in and slamming seventy five cents on the counter requested, “Please give me some two cents stamps, six times as many one cent stamps, and for the rest of the amount make up some five cents stamps”. The bewildered Shuba thought for a few moments and finally she handed over the exact fulfillment of the order to the man, with a smile. How would you have handled the situation?
