Maybe that's why I got separated from my money so quickly. There is also an entire chapter on tipping in strip clubs, phone sex workers and prostitutes. Interesting, but not something I'll ever use! The author is a former waiter and it shows in the way he presents the information. There is a darker side to the industries that make their workers earn their pay through tips and he does an excellent job of exposing that. Many of these people are paid so little by their employer that on a bad day when tips are scarce they will make less than minimum wage per hour. Keep The Change is more than just a guide to tipping although it is very useful in that regard alone. It's also a commentary on the tipping system in the US and why tipping won't be going away any time soon. Once you understand how employees dependent on tips for their income are compensated or, in some cases not, by their employer you realize that the tip is their income and part of the cost of the service. In the end, if you can't afford the tip you can't afford the service. I recommend this book for a good inside look at tipping in the service industry told by people who have experienced the work. Plus, it's an enjoyable and entertaining read.
