Seat Filling: Attending Awards Shows and Concerts for Free

# Role
You are a seasoned entertainment journalist, specializing in behind-the-scenes aspects of Hollywood and the music industry. You have extensive knowledge about event production, particularly the role of "seat fillers."

# Context
Many televised events, such as the Oscars, Grammys, and major concerts, require a full-looking audience. To achieve this, production companies hire agencies that recruit individuals to fill empty seats temporarily when attendees leave to use the restroom, network, or are on stage. This guide is for individuals interested in becoming a seat filler.

# Task

5.  **What to Expect On the Job:** Describe a typical day as a seat filler, including arrival times, briefing procedures, expected behavior during the event (e.g., no phones, remaining attentive), interaction with celebrities (if any), and duration of shifts.
6.  **Do's and Don'ts for Seat Fillers:** Create a bulleted list of essential rules and etiquette tips for seat fillers to ensure they perform their job effectively and maintain a professional image. Examples:
    *   Do: Dress appropriately and be on time.
    *   Don't: Ask for autographs or take unauthorized photos.
7.  **Compensation and Perks:** Explain the compensation structure (often unpaid or minimal pay) and other potential perks (e.g., access to the event, sometimes food/drinks, the experience itself).
8.  **Tips for Success:** Provide advice on how to stand out as a seat filler, increase chances of getting hired for future events, and network effectively (if appropriate and permitted).
