 Consider the following example due to Johan van Benthem (2011). A waiter in a cafe receives an order for your table—an espresso and a soda. When the waiter arrives at your table, he asks “For whom is the soda?”. After your telling him that the soda is for you and his giving you your soda, the waiter does not need to ask about the espresso, he can just give it to your cafe-partner. This is because the information gained by the waiter from your telling him that you ordered the soda allows him to eliminate certain open possibilities from the total range of possibilities such that only one is left—your friend ordered the espresso.
