I went outside, walked a few blocks, entered a building, asked for some food, handed over a piece of paper, was given hot, good food 2-3 minutes later, and left. I didn't bring ID, and I didn't give my name.
Sitting in the public area were bins with hot sauce packets, napkins, sporks, drink tops, straws, and a soda machine. No security.
My order was set on the counter. I walked up and took it. No one checked my receipt.
It's amazing how peaceful our society is.
