Apparently the food at "Raging Burrito" is mostly "Raging" with insect infestation. It seems to have become such a common occurrence that they've added a convenient button for it on the register — right next to the ones that say "FELL ON THE FLOOR" and "SOAKED IN URINE." On the bright side, this vegetarian got the nutritional benefit of some added protein. Some places charge extra for that.
