A poor merchant dropped in a village to spend a night in a house. He had a couple of coins and few items. The housekeeper thought, "Why shouldn't I take all his money and merchandise". She said to her husband, "There is a merchant staying in our house. It would be good to take all his things". Husband said, "Just put some herb named "mega" in his meal. Everyone who eats the herb forgets something". In the morning the merchant left early. The housekeeper woke up and the room was empty. He did not forget anything. The housekeeper and her husband finally started thinking. Suddenly she slapped herself on the forehead and said, "Oh no! He forgot to pay our bill"....
