Patrick,
It will come as no surprise to you I was angry when I started the thread - my anger originates from what, in my opinion, was the hypocrisy of the stadium management increasing costs to members when they have a stated objective of supporting membership growth.
I haven't responded to some of the answers given as they are either factually incorrect (e.g. surpluses are not used to pay maintenance, surpluses are after maintenance costs have been accounted for) or they don't address the problem as I see it (e.g. having a greater variety of food options and craft beer that are more or less the same cost as current food options doesn't solve affordability issues for families) or I simply don't believe them (e.g. Spotless have a contract that is, in effect, in perpetuity).
I believe there are major issues with the stadium's cost structure and there is poor collaboration between the providers of the range of services that make up the match day experience.
Whilst I think my questions are very valid my spleen however is better for the venting - just feel free to delete the thread if you are uncomfortable with the content or discussion.
