Casting assistants are probably frustrated. Probably having a bad day. Don’t take anything personally.
Just need to see the release! (if booked a job through LA Casting & not agent). If you are SAG, and book a nonunion commercial — tread lightly, but you can prob get away with it.
Book commercials: thank the casting director — send pictures from set.
Add everyone in the audition room to PDB!
Multi-week workshops (if you don’t have a ton of credits) establish relationships with casting directors better.
Juice cleanse — 5 days is enough/minimum to see & feel results.
