What is the author's tone in A Supposedly Fun Thing I'll Never Do Again: Essays and Arguments by David Foster Wallace?

Wallace's tone is frequently condescending to many of his subjects and occasionally even arrogant towards the reader. Wallace openly mocks many of his subjects. For instance, when Wallace is on the cruise in the titular essay, plays many games of ping pong against the ship's ping pong pro, Winston. Wallace is much better at ping pong and frequently pokes fun at Winston and the cruise in general while they are playing, but Winston never seems to notice or understand that he is being made fun of. In the same essay, Wallace describes watching other passengers go ashore in Cozumel, Mexico from the ship, and Wallace describes them as cattle. However, Wallace is aware that he stayed on the boat so that he would not appear like the other Americans, so he is still acting out of concern for his image. Though Wallace frequently pokes fun at his subjects, Wallace is usually aware of his own shortcomings and points them out to the reader.
