Ordering expensive items off the menu when you know the check is going to be split evenly between everyone.

Defensive dining insures that the amount you owe at the end of the meal will be the same or less than what you ordered.
Jim: John, if you are going out with the Bill and the Marketing team for dinner tonight you need to use defensive dining when ordering. The last time I went with those guys they ordered the most expensive things on the menu and I got stuck paying $10 more than what I ordered.
