Hat check boy (The Middle Men)
From Tardis Wiki, the free Doctor Who reference
This unnamed hat check boy took Jack Harkness's coat when he arrived at the restaurant where Stuart Owens was having dinner with his wife. He complimented Jack's vintage coat. Jack suggested that he, the check boy, and the coat get a drink sometime, and slapped him on the bottom; an offer that did not appear to be unwelcome. (TW: The Middle Men)
