Can you describe the specific worship routine Babasaheb Tarkhad performed after his son left for Shirdi?

After his son left for Shirdi, Babasaheb Tarkhad took over the daily worship himself. As detailed in Chapter 9, he would perform the worship after his morning bath. He would pray before Sai's painted image, asking that his service be as devoted as his son's and that he make no mistakes. The routine included a daily food offering, or Naivedya. Specifically, Tarkhad "offered constantly" a piece of sugar candy for the Naivedya. It was also his habit to consume this offered sugar candy as 'Prasad' when he returned from work for his afternoon meal.
