Law of reciprocity is an powerful arsenal in a realm of influence. Because, through personal experiences and reading several social psychology books and other related books has shown the difference in correlation between law of reciprocity and likeability. Especially, if the other person has consistently and indirectly done a favour of buying you something. For example, from personal experiences in living in London; prior to moving to Manchester—the very few people out of dozens of people, who made an effort to spend money on me, were able to increase their likeability levels. Thereby, I felt extremely pleased to enjoy their presence and maintain a close bond. Therefore, my personal testimonial based on experience can prove that a simple act of generosity has the magical effect of increasing influence and persuasion—during longevity of maintaining bond with others. Nevertheless, if you want to influence people and maintain a long lasting of fruitful bond with others— spend money on them. Because, the more money you spend on others, the more admiration you will receive in return.
