The way powerful people often maintain control of a situation is through contrivances such as unusual dress, unusual ways of speaking, unusual rituals or by having a large entourage.

If you analyse each element closely it's clear that they're silly. Why do they need earpieces in when visiting Apple? Why must all the cars match? Why must they dress in the same way? Why do they need to bring all those people, what are they all doing?

But the point is, when faced with something new and strange, people often pause and withdraw. This allows you to dominate the situation and prevent dissent.
