stupid restaurant concept

In my early morning slumber I dreamt that my family was driving through the mountains. Presumably we were all a bit younger again in this dream. At least it seemed that way. Anyways, the mountains were looming above us with their imposing precipices and my Dad decided that we should stop at a restaurant to eat. At the restaurant he asked what they had to eat, the waitress began yelling at him that we hadn't brought our own food and how were they supposed to cook us a meal if we didn't give them something to cook with. In the dream, it occurred to the much younger version of me that this was possibly the worst concept for a restaurant that I had ever heard.
