This book is very funny. And even though it was published in the mid 1990's, I think it is still actual, maybe even more so now than then.
The basic premise seems to be that good manners are just an exageration of who you really are, and here the book indicts most people. Nobody seems to have substance anymore, people have inflated ego's, especially those who are considered succesful. But there is an underlying tone which seems to suggest that if we were a little more civil to each other, rather than opinionated, society would be a much better place.
It is a book about Americans and how they can be extremely rude, while thinking they are quite polite. I am an European but there are lessons to be learned here. Especially as an increasing number of people seem to be "Americanized" (there is a warning here, I blame television).
Did I like this book? "Fuck, yeah!"
The book is probably best summarized in the final quote:
Etiquette is for those who have no breeding,
Fashion is for those who have no taste.
