This follows from a silly conversation over the weekend. One of those "is it more polite to eat everything on your plate or leave 1-2 bites" types.
Imagine you are in the supermarket. You are going to get a can of minestrone soup (substitute other canned goods if you don't enjoy soup). When you look at the other varieties of soup, there's usually a dented can with a discounted-price-sticker on it (reducing the price by about a third). There is one dented can of minestrone soup, but it hasn't been marked down.
Don't overthink it--answer as quickly as you would standing in the soup aisle.
