I wouldn't mind a policy that keeps the riff raff out and encourages more elites to attend games.
I can understand a student with the mentality that they need to take advantage of those 20 minutes between halves by running out and downing as many beers as they can (although I never did, and this was during all of the Prince years), but I think the adults should know better. As MIR said, you have as much time as you want before and after the game. If I could watch the Cats play with a frosty 8-bit in hand I'd never want to leave the stadium.
Catch up with your friends before and after the game. Make some new ones during.
