"Well," answered Percy, "I blush to tell you, but it was a moving-picture fella. He was the only man we found who was used to playing with an unlimited amount of money, though he did tuck his napkin in his collar and couldn't read or write." (8.4)
Here's another example of Fitzgerald's satire. He mocks the reputation of the movie business for spending inordinate amounts of money.
Quote 2
"That's nothing." Percy had leaned forward and dropped his voice to a low whisper. "That's nothing at all. My father has a diamond bigger than the Ritz-Carlton Hotel." (1.25)
At first, it's hard to take Percy seriously – and this is in part because we remember that he's a teenager trying to impress his friend. Age plays a big part on John's character, too, but in Percy's as well.
