Having driven over most of Europe and tasted the wares in both the Swiss and French alps I can assure you that their cleanliness, or lack thereof, never came to mind while I was eating those delicious cheeses, breads, butter, and other items. We once stopped at a inn in the french alps where I'm sure the innkeeper sold us his dinner. We had one vegetable and three or four different meat dishes. Probably caused by the lack of any fields in the area to grow vegetables. Very rocky area. Anyway, the meal was delicious. As we were on our way back to England we paid him in just about every currency you can think of. Great time!
