Only in 770 can you walk in for Maariv and see the Rebbe's secretary of many years standing in the hallway schmoozing with Avraham Fried and everyone just walks by without a second glance...
If you saw Rabbi Krinsky, then his daughter married Avraham Fried's brother...
But, yes, it's quite normal to see "celebs" doing their regular schedule and everyone walks right by..
That's a good thing, otherwise if there was constant paparazzi, it would be (more) impossible for many people to live normal lives in CH.
