Bill is the real deal
The 2-page guide to quickly catching a card counter is worth more than the price of the book, many times over. It is somewhat universal. Each casino's protection dept. has their own way to do things and different procedures for documenting us, but they all do the same basic things. This one has a few great moments that make it well worth the price in my opinion. But then again, I try to always "read all the books and get all the money".
