You are confused whether or not to trust him. If you do not trust him, you have to take it to another service center, which is far away and inconvenient. If you trust him, he can either cooperate or defect (do an honest job or not). If he does an honest job, both of you will gain from the trade. If he does not do an honest job, he will gain $500 while you will lose your money. Clearly, he will gain more by defecting rather than cooperating with you. Refer to the scenario above.

ultimatum game
