Elephant Dung Coffee: Smooth, Rich and Expensive
From the news that I saw originally a few years ago, the elephants were very well-treated, almost pampered. But then I guess it’s always a good idea to stay on an elephant’s good side when you have to see them every day. They may not think much of people that clean up their poop in the first place, kind of like how aliens may assume dogs are in charge since they see us following them and cleaning up their messes.
