I can't even talk in front of a group of people without feeliing like I'm going to pass out, so I assume that adding a claustrophobic, heavy latex prosthetic would probably just make me wet myself before passing out.
Or it might help counter the anxeity of talking in front of a group of people, and yes I dislike talking in front of even small groups of people.
But my answer to the OP's question is I don't know. What can happen is that people say they'll be fine with it until it's applied than they could freak out.
That's why they have make-up tests.
