A sardarji had a daily routine, going to office in bus and then returning home by it. One day he got late for the bus to return home. He ran after the bus and reached home running and huffing. After reaching his house he told his wife that he had saved Rs.3 by running after the bus and reaching home. Instead of getting an acknowledgementhe got a huge slap from his wife. Sardarji was puzzled? He asked his wife that why did she slap him. Her reply was, 'Ig you had run after a taxi you could have saved Rs.70 instead of Rs.3!
