Sustenance
Quorra didn't really understand why Sam was making such a big deal out of this. They had food on the Grid.
It wasn't really food though, really it was data streams packed into a food like shape but to Quorra it was basically the same thing. Data kept programs alive, food kept Users alive. The principle was exactly the same.
"No," Sam had insisted, "This is totally different."
So she had humored him. She got in the car (it was nowhere near as fast as her old roadster) and sat patiently for fifteen minutes until their car came to the head of the line. Fifteen minutes to Quorra was nearly an eternity and she demanded to know what was so important.
Finally they received the bag filled with the strange, paper wrapped objects and Sam eagerly handed her one of them. "Unwrap it and dig in."
She did and the sensation was almost unbelievable. How could one object taste so delicious? Quorra had to grip the side of the car to keep from fainting.
This was her first, but not last, In and Out Cheeseburger.
