Can you describe the humorous incident that took place in the darbar involving Annasaheb and the parched grains?

Chapter 24 recounts a curious and humorous incident that occurred on a crowded Sunday afternoon in Shirdi. While the narrator, Annasaheb, was performing 'Pada-samvahan' (massaging Baba's feet), Madhavrao Deshpande noticed something on his coat and laughed. He pointed out that parched grains were stuck to Annasaheb's sleeve. As Annasaheb extended his elbow, more parched grains, or 'futane', rolled out from the folds of his khaki coat. About twenty-five grains were collected, sparking great amusement and wonder among the devotees present.
