He ate breakfast each day in a pizza shop near the Yeshiva. Because the owner refused payment he always made sure to sit near a window so that it would help business.
FTFY. I saw him there. I was not aware that the owner never took money, although I do remember seeing him sitting by the window.
As his son said by the levaya, he sat in the back of the Bais Medrash until R' Moshe was niftar and he became RY.
He also wore a straw hat when the weather was nice.
Until his son in law took away the keys, he would stock the soda machine.
