Can you tell me the story about Sai Baba lighting lamps with water? I heard the shopkeepers wouldn't give him oil.

Yes, that is a well-known miracle. As narrated in Chapter 5, Sai Baba had a great love for lighting lamps and would beg for oil from local shopkeepers. After some time, the grocers grew tired of this and conspired to refuse him. When Baba came for oil and was denied by everyone, he quietly returned to the mosque. He took his tin pot, which had a tiny bit of oil left, added water, and drank it as an offering. Then, he filled the lamps with plain water, soaked the wicks, and lit them. To the amazement of the watching grocers, the lamps burned brightly all through the night, causing them to repent for their actions.
