What happened when another devotee criticized Mavshibai's intense way of massaging Baba?

The source material in Chapter 24 describes a separate incident where another devotee became concerned about Mavshibai's vigorous service. Seeing the 'excess' of her pressing, this person felt pity and worry, exclaiming, 'Lady, have mercy! Is this any way to press the body? ... Baba's veins will break.' Upon hearing this criticism of his devotee's service, Sai Baba's reaction was swift and severe. He immediately rose from his place, grabbed his Satka (a short stick), and struck the ground with it. His mood transformed into a 'terrible rage,' and his eyes glowed like embers, scanning the room in a way that no one dared to stand before him, showing his strong disapproval of interfering with a devotee's loving service.
