What was Mavshibai's style of service, and how did it directly lead to her conflict with Damu Anna?

Mavshibai's service was remarkably intense and physical. Chapter 24 explains that while serving Sai Baba, she would twist and 'grind' his stomach with both hands, pressing and churning as if it were a pot of buttermilk. She was so absorbed in this service that she would become breathless and sway back and forth. It was this swaying motion that caused her face to come near Damu Anna's face, who was serving from the side. This accidental proximity gave the 'humorous Mavshibai' an opportunity to playfully jest with Anna, accusing him of trying to kiss her, which sparked their temporary but memorable quarrel.
