Paul R. Timm's "50 Most Powerful Ideas You Can Use to Keep Your Customers" is a small book with powerful strategies to increase customer service.
This is a great option for students interested in hospitality/customer service or as a way for students to learn transferable skills and reading non-fiction text. While there are 50 ideas, I have only been able to get through the first 25 in my classes. The other half also build off of the first 25's basic ideas so at this point, this ONLY INCLUDES 25 of the 50 ideas. In time, I will add and finally finish the other half.
I like to use this as a warm up or as a weekly ongoing discussion about customer service as seen through the customer's eyes, the employees, and the manager or owner of the business.
Important: Although it uses a book and it can be expensive for a school to buy a class set, this is also a good chance to read this aloud to your students as practice for the CCSS standardized test that includes an auditory section!
