Surely Anita should have known getting a blessing from the eldest in the family, baa, was important in her journey to being accepted by the family as a prospective wife to Aham, so she lost sight of that aspect, no matter if Baa gave her nothing but just that blessing from the eldest is required for her hopes with Aham.
Anita didn't know the value of the sikka coin. But she also disregarded importance of the mala beads (like a muslim tasbeeh/christian rosary), as a prayer tool, and making an excuse not to fix the problem she created leaving the old lady like that without her mala, when she broke it... today she proved herself very much like Rashi.
