One of the distinguished chasidim of Sanz was a wealthy man named R' Avrohom Shmuel Shmaya. At one point, he lost all his money and became very poor. He was once sick and unable to go to the Sanzer Rov, so he sent his son, R' Yosef, to visit him on erev Yom Kippur and ask for a bracha on his behalf.
R' Yosef walked into the room, where a large crowd was already gathered. When the Sanzer Rov saw him, he stood up and yelled for everyone to leave the room. The crowd started filing out, with R' Yosef amongst them. However, the Rov grabbed his sleeve and motioned for him to stay.
After everyone else had left, the Rov gave him some money to give to his father. He then gave him a bracha for a refuah sheleimah.
The Rov sent everyone out so the young man wouldn't be embarrassed about taking the money. On the eve of the holiest day of the year, the Rov was concerned for this family and wanted to help them discreetly.
