According to the videotaper, after Thom saw him recording he walked up to him, stuck his phone in the guy's face, and asked the videotaper how it felt. Eek.
I would pee my pants or run in the opposite direction. I'm a little scared right now, tbh.
Note: Thom Yorke is the frontman of Radiohead, if you didn't know that already. Just so ya know.
