The Middle of Bavaria. Of course the airport had food. But I was 2 and a half hours away from an airport by autobahn. Every restaurant for dozens of kilometers around was closed.
I asked my hotelier about it and he just shrugged and told me where to get some kebab three towns over.
International travellers tend to arrive by plane or train (as Derbasti says), you can buy something from there. Or from a restaurant.
The only problem you would have is with supermarkets away from the train station or airport.
