I bought this book to use at work, as part of my job involves Customer Services. It was brilliant (in fact I read it all in one go) and it now lives under my desk! The opening chapter deals with general basics which are a useful reminder, however it's the rest of the book that earns its stripes. Just about every situation you could think of is presented clearly and concisely, each to a separate page, with examples of how a conversation may go and how to respond. I've encountered some super tricky Customers (you know who you are!) and this book has shown me how to handle them all.
I've now changed my Customer 'scripts' to fit in with the book and this has proved very successful, with some great feedback from happy Customers. Highly recommended to anyone with an interest in this area.
