St Luke's canteen
From Tardis Wiki, the free Doctor Who reference
The St Luke's University canteen was a place where students could eat while on campus.
Bill Potts worked there as a dinner lady. She once recounted to the Twelfth Doctor how she had given extra chips to a particular woman, in an effort to flirt with her. When finally the woman noticed her, Bill saw that the months of extra chips had made the woman fat. (TV: The Pilot)
