I was speaking to a friend a few days ago; she's a major donor to an organization. She talked about how this organization doesn't listen to her preferences but instead keeps doing what it wants even though she has specifically asked the organization to stop. It's probably inexpensive for the folks at this organization to keep her "in the program," and this can certainly be justified — except she has said, "Don't do that."
