Random terrible brainstorm idea: purchase the cheapest available airplane ticket for your delivery person for late in the evening. They can now pass through airport security.
Obvious problem #1 is that ordering drinks is now impossible, but what does a delivery service offer that in-airport restaurants don't?
Another obvious problem is that the TSA agent may arbitrarily claim that you can't bring in X pounds of food, all pre-packaged, into the airport - especially since it rapidly becomes obvious that you're handing it to a total stranger.
