This doesn’t have much to do with altruism or empathy. In your case: well-to-do people get more in return from managing their reputation as upstanding folks than the they would get from throwing a fit over something that they might only need to get fixed within the month. In the case of poorer people: they might have to pay rent today with that money, so their manners might go out of the window somewhat due to stress (getting mad because of someone else’s mistake doesn’t have to do with lacking empathy or altruistic feeling).
