Query: This book has no valuable information. It is bad, very bad.

If you have spent at least one week in the business world, and have any common sense whatsoever, you do not need this book.It is 58 pages of valueless tripe. An example comes from the author's chapter on Office Meeting Etiquette... "When it is raining, wear a raincoat to protect your clothing and an umbrella to keep your hair and face dry." This insightful gem is shortly followed by: "Have a pad and pen handy for taking notes during the meeting".However, if you find yourself needing to know how to address a king, queen, or president then this book is for you.This book (my copy at least) came complete with typo's that were hand corrected with an ink pen.Do not waste your money on this book.
