Explain the procedure you need to follow when using the restroom, including the amount of time given.
You have 3 minutes. You must be called first, and only one person can be up at a time. You will be called at 8, 10, 12, or 1:30. Walk along the path, check the restroom before using it, clean the restroom after using it, wash and dry your hands, and walk quietly back to your seat.
