I heard a story about Sai Baba and some grapes. What was the miracle that happened with Boss Dharamsee?

The story of Boss Dharamsee, found in Chapter 35, describes a beautiful miracle of Sai Baba. Dharamsee, a skeptical visitor, was mentally complaining because Baba was giving him grapes with seeds, which he disliked. As he thought this, Baba gave him even more. Finally, Baba instructed him to "Throw them in and eat." When Dharamsee obeyed and put the grapes in his mouth, he was astonished to find they were completely seedless. This experience shattered his doubt, causing his ego to drop away and be replaced with a deep love and devotion for Sai.
