I’ve seen pictures of that particular Rabbi, and I don’t think so, and at the time, I wasn’t aware of the names, so I don’t remember it.
However, he had that “following” that Rabbis of such repute had. Greatly loved by his people.
That’s really not uncomon. I tend to pack my food everywhere.
I travel a lot, so sometimes I end up with a an extra suitcase -— of homemade food.
