Why was Sai Baba so selective and stingy with his money, giving only to entertainers and performers who came to Shirdi?

The description in Chapter 29 of the Shri Sai Satcharita portrays Sai Baba not as stingy, but as a 'generous' and 'steadfast in charity' saint. The text states his fame for being 'compassionate to pilgrims' and distributing money 'abundantly' was widespread. While crowds of performers and singers did come to him, his charity was not limited to them. Chapter 29 explicitly mentions that he gave to 'the poor and needy' and would 'enquire about the poor and destitute.' The reason he did not give to everyone was attributed to his 'incomprehensible wisdom' and unpredictable nature. The text notes, 'he did not give to everyone - no one knew his mind,' suggesting his actions were based on a divine plan rather than stinginess.
