Serving in Florida

Ahh, the absolute hell that is working in a restaurant; I know this game.
Barbara Eirenrich's study in lower-class people working minimum-wage jobs is intersting, true to life, and yet oddly as if the reader is a visitor at the zoo, peering in on some exotic creature from some far-away land.  Maybe it's because I myself am not lower-class with a low-paying job, but I felt that her writing style made the reader feel too much like an outsider.  Perhaps it's because she herself was an outsider while she was working undercover. 
I myself have wroked in jobs with very low salaries, with lower-class co-workers, and I will say I was taken aback at times at their minimal ambitions and dead-end attitudes.  But they are still people, and should probably be portrayed as such.  I'm not trying to vindicate Eirenrich, but just saying that perhaps she should have spent more time on shaping the image of the people she worked with, rather than slander the jobs she was working, and therefore remind the reader that the person who serves them their fast food is indeed human too.
Otherwise, it was well-written and engaging, a good case of undercover journalism.  Just maybe she should have spent less time making us laugh and more time on sticking to the realism of that which is life for many many ordinary people.
