While there are things with this job that remain constant, in terms of how you shoot, the actual crux of the character is always different and always evolving.
I've sat in sushi bars, really fine ones, and I know how hard this guy worked, how proud he is. I know you don't need sauce. I know he doesn't even want you to pour sauce. And I've seen customers come in and do that, and I've seen him, as stoic as he tries to remain, I've seen him die a little inside.
