Dr. William Helmreich conducted an interview with Rabbi Yaakov Weinberg in 1978 as part of his research for his book, The World of the Yeshiva. Rabbi Weinberg was the son-in-law of Rabbi Yaakov Yitzchok Ruderman who was head of Ner Israel Rabbinical College in Baltimore and succeeded him in that role in 1987. According to Rabbi Weinberg (p24):
I lived as a boy in the Bronx, the Lower East Side, Brooklyn. I knew intimately what was going on. I can tell you something very meaningful. I took the chickens to the rabbi when there was a shailah (question) about them. I could go an extra 15 minutes to ask Rav Moshe the shailah. The reason I went to him was not that I knew he was a bigger gadol (great rabbi). They were all competent rabbis. But when I would ask a rabbi the shailah he would ask for the quarter. Until I gave him the quarter he wouldn’t look at the shailah. Rav Moshe never asked for the money. He answered the shailah. When I left, I left the same quarter.
