Yep.
Among my other duties, one of them is clapping the slate. Sometimes, you have no exit because the camera and lighting/grip equipment prevents you from getting behind the lens so you just have to crouch down in the corner off camera, typically facing away from actors so you don't get in their eyelines. I scratched my neck and I guess he heard it, because he said something along the lines of "would you PLEASE stop that scratching, it's very distracting!"
What can I say, some actors are pampered.
(on that note, some aren't, case in point Tim Roth on the same shoot was an amazing guy and would hang out with us, I think one time he even came down to the camera truck to play Halo with us camera folk).
