I used to work in a McDonalds, and I purposely served food that was made wrong, so that I would get a discount for myself

Sometimes when I was working on the food line, and the orders would come in, I would tweek them, so that the customer would get the wrong food. I would make sure that all the food looked good, and I changed the name on the order, but not the box. That way, I would have a full box of food to bring home, and because it was made wrong the manager would give it to me for a discount price. Once I made 2 large shakes for a customer, but at the last second I changed the orders, and instead of giving the customer the 2 large ones, I gave him the 2 small ones, and took the 2 large ones home.
