A group of "foodies" from a large city are traveling through a remote area and stop at a roadside diner to eat. They find a limited menu which features nothing but high carbohydrate, high fat, and fried foods. Finding it difficult to make a dinner selection one member of the group complains, in surprise, at the type of foods available. Another member of the group says, "Where you are and how you're dressed."
