Identify an instance of satire in the 1,000,000 bank note he hasn't yet been discussed in this lesson and explain its meaning in the text

"Here is one of several examples of satire you could have chosen from the story: The narrator says "Englishmen always eat dinner before they go out to dinner, because they know the risks they are running." Twain informs the reader that Englishmen are used to having dinner before attending a formal dinner, because they know it might be called off over the matter of who should take precedence at the dinner table. Twain is satirizing the petty egos of upper-class British society of the time."
