Dinner lady

Dinner ladies were people who served meals to students in school cafeterias. Typically, dinner ladies were behind a series of glass-covered heating tables, dispensing food to a queue of patrons. Rose Tyler once gave the Tenth Doctor the impression that the position was lowly and undesirable. (TV: School Reunion)

Bill Potts worked as a dinner lady in the cantine at St Luke's University when she met and was eventually tutored by the Twelfth Doctor. She once recounted to the 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)
