How and where does Krakauer show his disdain for Sandy Hill Pittman?

Sandy Hill Pittman, a wealthy socialite hired the Fischer's. Krakauer is very critical of her. She brings a lot of unnecessary gear by putting extra weight on the Sherpas. She is not prepared for the climb. She brings electronics and computers to write about how great she is. Krakauer finds her vain, self-absorbed, and disrespectful to the natives.
