In-N-Out Burger - Behind the counter look at the fast food chain

It's not new or specifically Tech-y but I feel this is a must read. First of all by fans, second by anyone who wants to know more about business. This is the essence of all that is good and pure \ smart and true in business. We're talking about much more than hamburgers here. There's methodology, there're principals and a lot of hard work. I would have added this book as a must read at any MBA program.
