Why did not the stranger tell the ironmaster that he was not Nils Olof. (30-40 words)

Although the peddler of rattraps had never seen the ironmaster at Ramsjo before and did not even know his name, he pretended to be who Nils Olof thought he was. It occurred to him that if a fine gentleman thought he was an old acquaintance then he might perhaps throw him a couple of kronor. Hence, he decided not to undeceive the ironmaster.
