I've heard a story about Baba climbing a ladder. Can you explain what happened and what the moral of that story is?

Indeed, Chapter 19 recounts a peculiar incident where Sai Baba used a ladder. One day, he suddenly had a ladder brought and placed against a house. He then climbed onto the roof and crossed over to the adjacent roof of Radhakrishnabai, who was suffering from a high malarial fever at that moment. After coming down, Baba insisted on paying the man who brought the ladder two rupees. When asked why he paid so much, Baba explained the core lesson: "One should not take the burden of anyone's labor for free, not even a bit." This leela teaches the profound importance of fairly compensating others for their work.
