While I don't usually get flustered or intimidated by bigshots, it was an interesting moment when Levi Leviev moved to our neighborhood (when he still had some money) and the first Shabbos he came to shul, when it came time for Borchu, seeing him in the front and the poor guy in the back, bowing to the same G-D.
While this Dr may not respond to Borchu, he obviously realizes that he has the same 10 fingers and 2 eyes as we all do and was created equal to us by the same G-D only that G-D gave him a different mission then he gave me.
