Why specifically were Tatyaba and Madhavrao so upset about Sai Baba's purchase of the goats?

Tatyaba and Madhavrao were so upset about the purchase because, from their practical viewpoint, Sai Baba had been severely overcharged. According to the account in Chapter 46, they knew that a goat was worth 'two rupees, or three or four at most.' However, Baba paid sixteen rupees for each goat, totaling thirty-two rupees. This seemed like an illogical and wasteful deal to them. The text from Chapter 46 mentions they were 'very agitated internally' and condemned the action because they saw it as Baba being cheated, and they could not understand the logic behind what they perceived as a 'bad deal.' Their concern was rooted in the monetary value of the transaction.
