Cialdini raamat
In most in-
stances, a small amount of the relevant product is given to potential customers to
see if they like it. Certainly this is a legitimate desire of the manufacturer-to expose
the public to the qualities of the product. The beauty of the free sample, however, is
that it is also a gift and, as such, can engage the reciprocity rule. In true jujitsu fash-
ion, a promoter who provides free samples can release the natural indebting force
inherent in a gift, while innocently appearing to have only the intention to inform.
A favorite place for free samples is the supermarket, where customers are fre-
quently given small amounts of a certain product to try. Many people find it diffi-
cult to accept samples from the always smiling attendant, return only the
toothpicks or cups, and walk away. Instead, they buy some of the product, even if
they might not have liked it very much
