The subtitle of this is: "The Unauthorized Adventures of a Front-Line Employee."
The author spent a year working at various retail-type jobs, and recorded his experiences. He worked at UPS, Starbucks, Gap, the Apple Store, and Enterprise Rent-A-Car. The behind-the-scenes aspect of this was interesting, but I was expecting more of a "Nickel and Dimed" approach. This is a journalistic account, rather than a sociological approach, but it was still interesting.
