If this woman deserves £20K for failing to do her sums properly, I should get a fortune for the way I keep managing to put two and two together and get results that really do add up!
Life doesn’t work like that in the real world – here, she’d be told to get over herself and get on with it; if she wants more money she can go find a different job (we’d ALL be better-off).
But she works in Toryland. She’ll probably get more.
