A double-double with "In-N-Out Burger" book author, Stacy Perman

In fast food corporate America, In-N-Out Burger stands alone. It's reached its cult status on the West Coast because of what it's not done: It hasn't expanded nationally, it hasn't leveraged itself to finance growth, and it hasn't changed its menu since the start. At In-N-Out, it's all about the burgers. WalletPop writer Julie Tilsner sits down for a double-double with the author of the best-selling "In-N-Out Burger: A Behind the Counter Look at the Fast Food Chain that Breaks All the Rules," Stacy Perman.
