There’s a difference between “using someone for their money” and “I enjoy my relationship with this person more than I otherwise would because they have the resources to provide more things for me”. You can’t honestly evaluate what your relationship would be like without his money, but you didn’t get into it for the money, and it doesn’t sound like you take advantage of him.
They would 100% do that if the roles were reversed, and thus they assume that yes, the EMTs would.
It is very difficult sometimes to remember these are people, too. Tells you a lot about how fucking stupid we can be.
