John:
Your post reminds me of a story a friend told me about, he was on Safari in Africa. He the PH and trackers were headed back to camp one afternoon and he had a large bag of M&M's in his pack which he opened and shared with the PH then offered some to the trackers, they just grabbed a handful and handed the bag back to Gene, he started to take some more and the PH said "I wouldn't do that, they don't use toilet paper!"
