Question

Why had the narrator never thought of going Foyot's​

Answer 1

Answer:

Part of the irony derives from the fact that the narrator has never dared to go to Foyot's by himself because he is living on a very small income; and further, he has to watch his voracious guest devouring gourmet comestibles while he has to pretend he only wants a mutton chop and a glass of water.

Answer 2

Answer: The narrator never thought of going Foyot because the narrator was living in a small apartment, and he was barely earning enough money to keep body and soul together. The second reason for this answer is that for the narrator "Foyot" was beyond his means so didn't go there.
