Barista (The Bells of Saint John)
From Tardis Wiki, the free Doctor Who reference
A barista in London served two cappuccinos to the Eleventh Doctor in 2013. After this, Rosemary Kizlet used the Wi-Fi to speak through him. Kizlet told the Doctor that he didn't have "the slightest chance" of protecting Clara. Kizlet then ordered everyone in the café to clear the room. (TV: The Bells of Saint John)
