This is proven by introducing money to monkey communities.
Monkeys were getting plastic tokens of different colors for their work, and behaivor. Different color tokens had different value. Blue one could buy a banan, red one several grapes, black one - could buy nothing.
Eventually, monkey were not interested in black ones, but would fight over other color tokens, even more, female monkeys would hang out more with those males, that had a possesion of more tokens in their corners...
Money can creat arguments even among monkeys, so friendship should be free of money responsibilities. 
You've got to be joking. You take a study on monkeys to prove a point about humans?
As cute and intelligent as monkeys may be, they are not humans. We all have financial dealings with friends and those people who have problems with such interactions will usually have problems in other areas too.
Gonesh obviously has great integrity and wants to do the right thing for his friend. With that being his desire he is sure to keep his friends. If he was asking how to get out of paying up, he would not only be failing a financial challenge, he'd be failing a basic honesty and integrity challenge. Those sorts of people don't keep friends long even if money isn't involved.
