In The Catcher in the Rye, Holden (the protagonist) is found eating breakfast on a Sunday morning. After helping the nuns with their suitcases, Holden asks them if they will allow him to make a donation to their cause. Holden donates ten dollars to the nuns.
After making small talk (about Shakespeare and his play Romeo and Juliet) with the nuns during breakfast, Holden offers to pay for the nuns' breakfast. They both refuse.
Holden, after the nuns leave, begins to think about the lunch he has just shared with the nuns. Holden becomes saddened when he thinks about the fact that the nuns never get to go to "swanky" lunches.
