Have you watched Better Call Saul, where the main character Jimmy specializes in Elder Law, befriends the residents of a senior citizen home and plays bingo with them, and turns them all into clients?

You could say he is being a bit manipulative there, or you could see the other side of it, that Jimmy is actually genuinely interested in the seniors, he cares for them, wants to protect them and give them the best possible service, and make sure no one else rips them off.
