Reading this book was like revisiting an old services marketing course. This book is written by Terry Green, a guy who has been in to Queue management business for over 20 years. So, it is more a practitioner’s book written to help supermarket chains, banks, or any establishment that deals with customers who form a Queue to get serviced.

[[The authors of this book run “Uncommon Schools”, a network of 32 charter public schools across Massachusetts, New Jersey, and New York.
