Can you describe the contrasting styles of service that Damu Anna and Mavshibai were performing when their dispute arose?

Damu Anna and Mavshibai displayed very different approaches to serving Sai Baba. Chapter 24 details that Damu Anna, an older man, was performing his service calmly by leaning forward and slowly pressing Baba's left hand. In stark contrast, Mavshibai, a widow of mature age, was serving with great physical intensity. She was so absorbed in her devotion that she was vigorously "grinding" and churning Baba's stomach as if it were a pot of buttermilk. This extraordinary and fearless method of pressing caused her to sway, which ultimately led to her face coming close to Anna's and sparking their quarrel.
