"John, it is apparent that you must have learned nothing in 4th grade history. If you had you would know full well that you yourself are the decendant of immigrants and know they did not speak standardized english. If the world were to operate on the premise of this is America then technically speaking we should all be speaking in various Native American Languages by each tribes territory. Furthermore if you would open your eyes far enough past your own nose you would see the same things as those who frequent this establishment. Casa Fiesta is the cleanest in town, the workers are constantly productive, pleasant, willing, and capable staff with exceptionally great service, and consistantly recieve the highest marks from the health dept . Furthermore they do understand english I assure you and they are all here legally. Perhaps they couldn't understand what you were saying due to you having walked in with a stick of predudice up your arse. I have been a loyal Casa Customer for years and know for a fact that this is the best restaraunt in town. Besides how much more Authentic can the food be when the restaraunt is Mexican and you have Mexicans fixing Mexican food, the food of thier heritage. Perhaps John you should stick to your heritage of hamburgers, and french fries?"
