Money Diary: TV Production Runner On 22k

Welcome to Money Diaries, where we're tackling what might be the last taboo facing modern working women: money. We're asking a cross-section of women how they spend their hard-earned money during a seven-day period – and we're tracking every last penny.
This week we're with a freelance production runner on various television programmes, which she says is both super exciting and super unglamorous at the same time. One day she'd like to be a comedy producer.
She is from a small Welsh town, where the idea of being freelance isn't a familiar one, and has only been living in London for 10 months. She has, however, managed to burn through a hefty chunk of money in that time as she has a penchant for expensive London restaurants. Traditionally, she was a saver but London seems to have changed that. Working freelance means that her pay can be rather sporadic and variable from one month to another and her working hours are all over the place.
