The difference is that our concessions shouldn't be priced the same as we are not paying for the player's salaries of the New Orleans Saints. We have athletes and they are not paying for tuition, they are on scholarship (most of them anyway). $8.50 for a 32 oz beer is not a good deal when I can buy a 12 pack of beer for that price.
I don't think you should be able to get beer for $.50 but $3-4 seems fair. The whole point of going to these games is to have a good time and if it breaks me to go to games then i can promise you that I am not going to have a good time. I'm not looking for things to be free but make them at least reasonably priced.
