As the Everyone Calls Him "Barkeep" trope says, some characters have the misfortune of being known only by their job title. His Name Really Is "Barkeep" is about those rare times where Everyone Calls Him "Barkeep" because "Barkeep" is the guy's actual name. May happen as a result of Who Names Their Kid "Dude"? Alternatively, maybe the guy had his name legally changed to "Barkeep" because he likes that name better than his given name. Patronymic can be considered a subtrope. Closely related to A Dog Named "Dog", when something is named for its species.
