A book by George Orwell about his experiences in the 1930s as a "plongeur" in a Parisian restaurant and a wandering indigent mendicant (more or less) in England. He concludes that the life of the poor was at the time a great deal worse than it needed to be. He generally backs this up, except that one of his problems was the difficulty of keeping up middle-class appearances. He was in agony over admitting to anyone, particulary tradespeople, that he had become poor. Well, I grew up middle class, and I've been poor, and keeping up appearances was the least of my worries.

The Paris episode put me off eating in restaurants for a couple of years.
