Still thinking about that one time when I shot a training video as a freelance gig, and later on, watching the footage again, I realised that the talent was probably drunk. He was so nervous about being in front of a camera that he got drunk to relax a little. It's like Nancy Pelosi. I remember watching a live broadcast of her on CNN and I realised she was drunk. People will drink to numb their feelings before going to work, so they can think logically and endure the stress.
