Exclusive Or/Examples/Tea or Coffee

Example of Exclusive Or
Consider the sentence that may be found on the table d'hote menu of a restaurant:


 * Breakfast includes either tea or coffee.

It is usually taken for granted that this is an example of an exclusive or statement:


 * The diner may include either tea with breakfast, or coffee with breakfast, but not both.

The usual understanding is that if the diner wishes both, then extra is to be paid.
