Bu99er that; press the button and stay to ensure the FA makes it quite clear to the little scrotes what they will do and what will happen if they don't. In 15 minutes they'll be out of your life.
PaperTiger, you are welcome to your view, but, as someone who travels once a week on average, I have found it better to leave these situations to the CC to deal with. They have the authority and training to deal with such situations.
Otherwise you tend to become part of the problem and potentially make the conflict worse.
