Food waste has always been a real bugbear of mine but like most people, I hold a particular bias. Although no one likes to discover some long forgotten food item in their kitchen that has clearly aged well beyond its use-by-date, I absolutely despair when something that was perfectly edible and especially tasty is needlessly wasted. Therefore, for purely selfish – or perhaps, more accurately – greedy reasons, it really pains me when the discarded foodstuff in question is something that I like to eat. Which is why when I read in the media about the recent arrest of a couple of spies for espionage-related charges I shuddered with horror. Not because they had been trying to sell secrets about nuclear powered US submarines in an eerie Vigil-like copycat. But that the spies had concealed an SD card containing highly classified information with a message wrapped in plastic inside half of a peanut butter sandwich. It was used in a ‘dead-drop’ in an outrageous abuse of peanut butter!
