I heard Damu Anna was involved in a dispute over the cotton trade in front of Sai Baba. Can you explain what happened?

The provided text does not mention Damu Anna being involved in a cotton trade dispute. Instead, Chapter 24 describes a personal quarrel between Anna and another devotee named Mavshibai. While they were both serving Sai Baba by massaging him, Mavshibai jokingly accused Anna of trying to kiss her when their faces came close. Anna, an older man with no teeth, became angry and rolled up his sleeves, denying the accusation. The conflict was not about commerce but a personal misunderstanding that Sai Baba cleverly defused with humor, highlighting the guileless love between devotees.
