'Spam talk' reminded me that back in the mid-80s I made a big gun trade. The guy threw in some rations intended for fallout shelters. Some wasn't bad but some was really bad. Anyway the guy told me that if you were in a survival situation and someone dropped by wanting a handout just to give'm the really bad tasting stuff and that they'd leave pretty quick and not come back. He also felt that word would get around and no one would try the take your stuff by force because they knew it tasted like crap. This actually makes some sense.
