Monetary systems are (very poorly designed, highly lossy) attempts to quantify trust in many dimensional axes. Corrode trust, then the cost of trade goes up. When I notice decisions made by people like what your friend does, if talking about it doesn't produce a change in choices, I instantly distance myself from them and then gradually cut them out of my life. Ethics is what you do when you think no one is looking on. Your mileage may vary, but personally, I have too little time in my life to spend on people who I have to worry about whether they will screw me over if the situation is just right. The cognitive load is not worth it.
