Barista (The Bells of Saint John)

This unnamed barista served coffee in a London café. After the Eleventh Doctor ordered two cappuccinos from him, Miss 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)
