I actually had an idea about this late last year. The problem comes when the traffic trying to move through the concourse has to cut through the concession lines. I was thinking why doesn’t someone develop an app for the stadium that allows people to order and pay through it and then receive a text message or notification once it is ready? The biggest obstacle I see to this right now is that they would have to seriously upgrade the wi-fi/cell capability in the stadium.
