Nowicki was not vindictive, but he believed that misconduct should be punished. He could not report the incident to the police, he absolutely could not cause a scandal, but the Italian should pay for his act, so Andrzej had a sincere desire to abuse him a little.
In addition to what Nowicki also admitted to Dominik, that he felt great gratitude towards Mrs. Janka, because she hired him at a time when he really needed this job and she did not try to take advantage of his desperation, but allowed him to develop. He felt that he should pay her back with a good of the same size, and the contract with J. Acutti was something any agency could dream of. So Andrzej was willing to sign this contract... right after he had a little bit of abuse about this Italian.
