Seems the human mind is wired to be sensitive to the concept of fairness. From what I understand it's been observed in chimps as well. At any rate, people see giving out things for free after they themselves paid for it as unfair, and most people react to that. It's not the logical reaction, as you're pointing out, but it is instinctual. This isn't exactly the same case, but I believe it's close enough to be applicable: http://en.wikipedia.org/wiki/Inequity_aversion http://en.wikipedia.org/wiki/Inequity_aversion
