Query: THE book to read on how to earn and retain customers

This book provides an invaluable education to any business owner or marketing /customer relations professional. You'll learn -- and also be refreshed on -- both common sense and sophisticated strategies and tactics for keeping customers coming back. I have become so much more aware of what constitutes a great customer experience because of this book, both as a consumer and as a business owner. Jill Griffin has done her homework, writes well, and shares great tips and examples. A great read. (P.S. Jill is also a great speaker!)
