My contribution to the rapidly growing W.C. media frenzy is to make sure you don't miss this quote from the Sunday Star-Times by David Allott, Eden Park Catering's venue manager, explaining why caterers have to serve beer in cans (which can be thrown, and hurt people, unless they're opened first, but caterers are complaining that it'll take too long to do this) rather than plastic cups:
"Eden Park does not have the infrastructure to wet pour beer into the public areas of the stadium."
