I have no food. I have about a dollar to my name. I went to the supermarket, hoping to turn that dollar into macaroni and cheese.
The gods smiled on me.
The macaroni rang up as $2.29; the shelf said $1.99. According to Stop&Shop policy, if something rings up incorrectly, you get one for free.
It took a half hour of arguing with managers, but eventually I got my free macaroni.
