Customer Service is Critical: A Manager's Primer
by Woodrow Sears
This book was begun 20 years ago, and shaped by interviews with two world-class hoteliers. They are among the finest managers I've ever met. In the intervening years, I've found that their ideas about management and what managers do are fundamental, no matter what your job or industry, and absolutely essential for providing professional customer service. Reading it will be well worth your time.
