At the risk of coming across as holier-than-thou...
I will never understand the need for anyone to leave the stadium for a beer (or two or three or more) during halftime--or less than half an hour prior to the game for that matter. If you can't go four or five hours without a beer, you have a problem. Get help.
There is a simple solution to people leaving for beer. Bring a flask.
For all you alcoholics that ABSOLUTELY NEED to come back to the game late, problem solved:

Now you can stay comfortably in your seats, socialize with your sectionmates, and enjoy stellar halftime entertainment courtesy of the ISUCF'V'MB!
