Waitress (The Bells of Saint John)

From Tardis Wiki, the free Doctor Who reference

A waitress served at a café in London. In 2013, Rosemary Kizlet took over her with the Wi-Fi, explaining to the Eleventh Doctor how she was doing this and how "impossible" the situation of protecting Clara Oswald was. Kizlet then ordered everyone in the café to clear the room. (TV: The Bells of Saint John)
