Here in San Diego, we had Tight Pants Tony come and give a talk at our Circuit Assembly (Spanish circuit, using a translator for his talks) about 2 or 3 years ago. Since this was before JW Broadcasting, GB members didn't yet have the type of "celebrity status" they enjoy these days, so most things were pretty low key. From what I remember, he sat towards the front of the Assembly Hall, but still in the general seating area, close to where the backstage area could be accessed. He was available for people to go and say hi to him and his wife and take pictures with them. But he got the same type of reception that most other Branch reps usually got. But since he doesn't appear very "personable", I think most people didn't feel too inclined to go out of their way to go up to him and greet him. From my experience, at least in our circuit, if the speaker was really good and looked very personable, people would make an effort to go up to them after the assembly and say hi. With Tony's case, before the assembly was over, they made it a point to say that Tony would not be available after the assembly to go up to and greet him, since they had to fly out right away and head back to NY. To me, that sounded like BS since I had heard from someone else that he wasn't due to fly out until the next day. So I assumed he just didn't want to stick around too long after it was over.
The only other time we had a GB member come and visit was for the Assembly Hall re-dedication (after a thorough re-model). I think this might have been before JW Broadcasting as well, but the crowd was a mixture of both English and Spanish speaking congregations. Stephen Lett came down for that, and he got quite a different reception. After the program was over, he was swarmed by a huge group of people, as if he was a rock star. People were pretty much just trying to get close to take a picture with him. It was a mob scene really. I'm sure he probably didn't feel comfortable with it, and I'm pretty sure he got this type of reception because most people find him "personable" and just eat up the way he gives talks.
