There are probably few people still around who remember the old crank phones and party lines where you had to wait your turn to make a call, and you could hear everything everyone said on your party line. A few years back, while on an expedition in the Amazon Jungle I was lucky enough to visit a farmer there who had an old crank phone made in France. I traded him a portable typewriter for it. He thought he screwed me royally, and I thought I screwed him too. It's nice when both parties are so satisfied with a transaction.
