I did hear another story from another Rav, Sorry I forgot his name. He used to go to some office every year and collect a check from someone who wasnt religous. It wasnt a huge check, but it was a decent amount
Then the man died and his son took over the company. The Rabbi went to see the son about the donation. The Son cursed out the Rabbi and threw him out of the office and told him never to come back. The Rabbi cried and his advisor said, Why did the Rabbi cry and the Rabbi said the donation was the only link the father had to yiddishkeit, Now the son refuses to continue that link there is no more link and he was crying because of that, not because he was thrown out of the office and told never to return
