I found an airbox full of dog food once. I walked into the waiting room and told the customer that they need to stop feeding their dog outside. They looked at me like I was some kind of psycho stalker.
It was an older caravan with the sideways air filter- poured all over the ground when I opened it. There was kibble all up under the hood 'blanket' too. By the time I emptied every thing out, there must have been 15lbs of food all over my bay.
