When people get stupid.
When people come to you less than week before you shoot again and go "Oh, nothing much has changed. We just have two guests not one and oh, there's a performance now that we need lit too. Two performers. not sure where we'll put them yet."
Just...
FUCK.
YOU.
Your stupid show is already using just about every light in the studio. And you just spring this on me now? Seriously? It's been two weeks since we shot last! Did nobody even think during the tech rehearsal or pilot that you need a performance space lit? I could have planned that into the original plans!
If you make me redo the entire lighting plan in my head, I'm going to kill someone. Seriously. (Yes. Partly only posting this here so I can use the icon..)
