I can tell In-N-Out Burger has extremely high standards because the service is always amazing and the burgers are in a league of their own. What really keeps me going back is the service chicks who operate the voice box/ window. They're unusually friendly for human beings who live in the 21st century. I mean, it's like they have no stresses and simply love operating a burger window. It's almost as if it's their "calling". All joking aside, In-N-Out has top-notch customer service. Great job!!!
