Barman (The Wedding of River Song)
From Tardis Wiki, the free Doctor Who reference
This Barman was a red-skinned humanoid who worked at a bar in the docks of Calisto B. The Eleventh Doctor went to his bar and asked him for Gideon Vandaleur. The barman denied he was there. He fetched Vandaleur after the Doctor showed him a Dalek eyepiece. (DW: The Wedding of River Song)
