This is where rationality and logic meet. If, upon landing, you knew that the other person had broken their own radio in order to avoid work, you would most likely meet up with them anyway. Being that you are away from civilization and will only be picked up upon rendezvous, it is in your own best interest to meet, and then reveal the other’s deception upon pickup. Even if you are not given their share, you still have your own, which is the original goal, and you have not lost anything. Also, the work that it may have taken to reach a coordinate acceptable to both persons may be equal or more than the work put out if you had gone straight to the other person.
