Answer:
The treatment that the cartonist gives to cooper and plumber is rude and inelegant.
Explanation:
The cartonist behaves in a bad manner, petty, inelegant and impolitic. He shows that he is a very uncomfortable person and does not mind humiliating and devaluing others.
This behavior shows that the cartonist does not have "chivalrous" actions and acts in a somewhat rude and inappropriate manner, which prevents us from seeing him as an educated, delicate person with a profile closer to what is considered a gentleman.
