My grandfather in Colorado did the opposite once in the 1970s. He needed some cattle, so he bought a small quantity of cattle futures of some form (I was too young when I heard the story to remember the details) from a broker/commodity trader in Chicago.

When the contract approached the settlement date, the broker called to ask him to sell. Trouble was, my grandfather just wanted cows, not cash. The broker was frustrated to no end.

Long story short, my grandfather got the cattle, as the contract required, but was asked by the broker never to do business with them again.

N.B. Don't do this unless you're interested in financial silliness, or if the futures are really badly mispriced. It is a lot easier, and you get to see the cattle first, if you buy through a local cattle auction.
