I guess she regards the food she buys for her work a business expense? Not sure if she now 'works' as a sole trader or not.
But it's always been weird for her to bang on about £20 shops when she can/could literally live of her business and eat the food she cooks for her recipes. I mean, not weird but disingenuous to pretend she lives of a £20 as some kind of inspirational thing. The fact is is that it is bleeping hard to live of a £20 shop and it's insulting to those who live on much less income than her.
Quoting myself llike an asshole here, but even
if she would live of a £20 for a year, or even a month, it would still not be the same as she will always be able to get money from her family/will have an inheritance at some point/has her passive Patreon income she could save up while doing that challenge etc.
Budget cooking as a challenge or hobby is so different to having no other choice and no hope of improvement in the foreseeable future (or worse, with the expectation of more cuts and higher costs coming at you soon). This is why students tend to not be
that desperate about their situation, as they expect at some point they will have some more expendable income, so it's more a rite of passage to be skint as a student than a depressing fact of life. And she almost never acknowledges this either, instead she'll write some emotional drivel about a thing that happened a decade ago for a limited amount of time.
The media is awful for continuing to give her a platform as well.
