Some traders - at shows and at some rendezvous - seem to have "flexible" morals about their deals. Any of us who have been doing this for long have run into them. My personal reaction is to avoid them in all future dealings and to pass the word to any other potential customers when I have the chance. In my opinion, they are in the same class as sneak thieves and bunco artists. The "flip side" of the situation can be seen with some (sadly, very few) people who value their word above their wallets. One such rendezvous trader made a deal with me for some gear, delivered the goods and was paid the agreed-upon price. Later that day he showed up at my camp, handed me some cash, and said, "I thought about it and decided I charged you too much." When I said I was happy with the deal as it originally was, he said he just wouldn't feel right. We became friends and did more business together over a long period of time.
I reckon it's likely I'm a dinosaur, but if I know a man's person's
word can't be trusted I just won't do business with him (or her).
