I think the interesting issue with the OP is the (rhetorical) question that the GB asked the R&F in the WT from last year..... let's look...

We can show Christian love by the way we treat those taking the lead in the congregation. At times, well-known representatives of the Christian congregation — perhaps circuit overseers, Bethelites, members of the Branch Committee, members of the Governing Body as well as their helpers — may attend a convention or theocratic event that we also attend. Naturally, we want to show such brothers and their wives due respect. None of us would want to imitate the attitude of Diotrephes. He refused to welcome the visiting brothers with respect. (3 John 9, 10) But could we, even unintentionally, show a lack of good manners by going to the opposite extreme? How might we do that?
While we appreciate having an opportunity to meet and talk with visiting brothers and their wives, we would show a lack of respect if we treated such ones as celebrities. For example, would it show good manners to take candid photos of such ones—without permission—while they are eating and engaging in other activities? Would we ask them to autograph our books and Bibles? Would we push in front of others and aggressively demand that our photo be taken with them? Surely, none of these actions display true Christian love. Rather, they could show that we have missed the purpose of the visit and the hard work that such faithful ones do in our behalf. What effect could such behavior have on those attending one of our assemblies for the first time?

For example, would it show good manners if we take photos of themwithout their permission or when they are not aware of it, perhaps when they are eating or doing something else? Would we ask them to sign our books and Bibles? Would we push in front of others and insist that we have a photo taken with them?
