I appreciate the attempt to send a message to the board, but I cannot agree that a 27 minute walkout is a good idea.
I don't think the super blues on twitter realise most of the match going fans don't follow them or use social media and most I've spoken to have spoken against it.
It's a game where we need to support the team, some of the concourses are too small for a mass pile in (main stand, bullens and upper gwladys) and it'll no doubt rile up some of the fans who have will be disturbed trying to watch the game. It's also a bit selfish, this could be some young childs first game and instead it's getting impacted by a useless inconvenience.
Seriously - why not just protest outside the ground or make more banners? I can imagine fans of other teams will find this funny - and also the players will be confused... "Where've they gone?... Oh they're back again never mind".
