He also tells him that he will ask his competitor to test the wine if he doesn't have time. Of course, Fortunato takes the bait.
Fortunato's arrogance, condescending attitude, and insults towards the narrator's wine expertise support the narrator's belief that Fortunato is unworthy of respect or sympathy. Additionally, Fortunato's betrayal and mockery of the narrator's family motto further solidify the narrator's hatred towards him.
The narrator pretends to be agreeable to Fortunato as part of his plan to manipulate him into entering the catacombs. By disguising his true intentions and appearing friendly, the narrator is able to lead Fortunato to his demise without raising suspicion. It's a way for the narrator to deceive Fortunato and carry out his revenge.
The narrator snaps and vows revenge on Fortunato due to Fortunato's insults and perceived disrespect towards him. Fortunato's insults, combined with the narrator's jealousy and wounded pride, eventually push him over the edge and drive him to seek vengeance.

He entices Fortunato with the promise of tasting a rare and valuable cask of Amontillado, knowing that Fortunato's ego and desire to prove his expertise will make him eager to go with the narrator to the catacombs.
The narrator of "The Cask of Amontillado" is Montresor. He tells the story of how he seeks revenge on Fortunato, ultimately leading to Fortunato's demise.
The narrator first saw Fortunato at the carnival in a drunken state, appearing to be happy and celebrating.
The narrator in the beginning of the story tells that he has evil intentions for Fortunato, because he feels that Fortunato had insulted him (in some manner). Fortunato, however, is the narrator's friend who was oblivious of the narrator's intentions because of the fact that he was drunk from the fair that he left from. However, he snaps out of his drunken state once he realizes that the narrator had chained and sealed him inside of his own dungeon.

The narrator says he has permitted a "thousand injuries" from Fortunato, but as the story develops, the reader wonders if those are all in his head. When the narrator meets Fortunato at the carnival, Fortunato is nothing but pleasant and helpful. All the time he is with Montresor he suspects nothing evil at all. The complete absence of animosity and fear of Montresor is hardly consistent with someone who has committed a thousand injuries against that person.
The narrator calling Fortunato his "poor friend" is ironic because it can be interpreted in multiple ways. It could mean that Fortunato is both unfortunate in being the narrator's friend and also lacking in wealth or standing. This ambiguity adds to the narrator's deceptive and manipulative nature in Edgar Allan Poe's story "The Cask of Amontillado."
The narrator is happy to meet Fortunato because he sees him as a potential victim for his revenge plan. He views Fortunato as someone who has wronged him and is seeking to get revenge by luring him into a trap.
