What was the reaction of the grocers who denied Baba oil after they witnessed his miracle with the lamps?

After the grocers refused to give Sai Baba oil, they watched to see what he would do. When they witnessed him light the lamps with water, they were utterly amazed, with the text in Chapter 5 describing them as putting their fingers in their mouths in shock. They immediately felt repentance, realizing they had sinned by lying to Baba and causing him needless trouble. The scripture states that as the water-fueled lamps burned all night, the grocers, feeling unworthy of Sai's grace, began to tremble everywhere, fully aware of the divine power they had wronged.
