Probably the best known persuasion point in Dr. Robert Cialdini's book, Influence, The Psychology of Persuasion, says humans aim to treat others as they’re treated, meaning that we have an innate instinct for returning favors and paying back debts. This is called the theory of reciprocity. This theory makes us feel obligated to offer concessions or discounts to those who have extended the same to us—because we’re uncomfortable when we feel indebted to someone. Many people may have missed the point that, "A defense against reciprocity would be to reject the initial offers or concessions. If you redefine them as tricks or ploys then you no longer feel obligated to respond reciprocally, unless you know the other person and can trust that the initial favor is given meaningfully." The latter point is critical!!! If you give something with an intention of getting something in return, your "give/gift" is voided. The point is, your "give/gift" MUST be given WITHOUT any thought or expectation of a reciprocal "get/gift." DO NOT USE the "law" of reciprocity with expectations.

Exactly!
