Can you describe the distinct styles of service being performed by Damu Anna and Mavshibai right before their argument?

Damu Anna and Mavshibai were serving Sai Baba in very different ways just before their argument. Chapter 24 describes Damu Anna, a man over fifty, as 'leaning forward from outside, slowly pressing the left hand' of Baba. His service was gentle and steady. In contrast, Mavshibai, whose original name was Venubai Kaujalgi, was performing her service with extraordinary energy. The text states she was 'twisting with both hands' and 'grinding' Baba's stomach, pressing and churning 'like a pot of buttermilk.' It was this fearless and engrossed method of service, causing her to sway up and down, that led to the incident with Anna.
