I’m in New York and going to be shooting outdoors for a few days this week as background for a major feature film. Even though I’d act the same during any shoot (short, student film, etc.), what are some not so obvious dos and major don’ts?

I know the obvious like “be on time” or “it’s going to be a long day” or “don’t take pictures” (they’ll be stickering our phones) or “don’t be weird to the stars/crew.” Beyond the professional baseline, what should I know? Can I bring a book? Should I bring a snack? What lingo should I listen out for? etc.

I was fitted for wardrobe so obviously I’ll take care of it/be clean, but also anything in this topic?

Thanks!
