I went to the gabba test with 5 mates & have a reasoning (or at least contributing factor) behind declining crowds & interest in the game.
When entering the gabba we were told we couldnt bring in a back pack as it had more than 1 zip, yes thats right cause it has 2 zips. Also a mate couldnt wear a baseball cap as it has a maccas symbol on it, a small one. Now youd suspect this was a directive of KFC being a sponsor yet their were maccas advertisments around the ground. Finally I couldnt bring in a water bottle, told I had to buy it from in the ground (they relented on this by day 3 so long as it wasnt opened).
Cant tap a beach ball around, start a wave, skull a beer, scratch my arse or generally look like you might be enjoying yourself.
Now I may be exagerating a little but I think they should be doing all they can to make attending the longer forms of the game (that make them the most money) as enjoyable as possible.
