What caused the conflict between Damu Anna and Mavshibai while they were serving Sai Baba?

The conflict between Damu Anna and Mavshibai, both mature in age, arose during their service to Sai Baba. As described in Chapter 24, Mavshibai was vigorously massaging Baba's stomach, causing her to sway. In this motion, her face came very close to Anna's. Seizing the humorous opportunity, Mavshibai jokingly accused Anna of trying to kiss her, asking if he had no shame for his gray hair. This accusation angered Anna, who rolled up his sleeves and retorted that she was the one who brought her face close to his, thus escalating a joke into a quarrel.
