The waiter was a Clockwork Droid who "worked" at Mancini's Family Restaurant. He asked the Twelfth Doctor and Clara Oswald for their order, until the Doctor realised that the menu was blank and that they were the menu. He then proceeded to rip off the waiter's face, revealing its metal interior, and then the Doctor asked if there was a children's menu. As the Doctor and Clara started to sink into the bowels of the crashed SS Marie Antoinette, the blank-faced waiter ended the conversation with these words: "Yes, we have a children's menu."
