If she could afford £10 per night for a takeway then she could afford salmon. I did wonder at her mentioning her debts in a very hopeful voice, perhaps wishing that Jamie would step in.
I'm on benefits at the moment, not ideal but it won't be forever. Since dts were born I've worked on a fairly tight budget and have always ensured they have fruit and veg and decent food, I taught myself to cook starting with an Annabel Karmel book from the discount book shop. It doesn't cost as much as they were making out. Poverty is not having a roof over your head, it is not found with a huge cooker. And cookers are not supplied in council rented accommodation.
A lot of my neighbours have these loans where someone comes to the door to collect payments. When they describe how it works and how much they pay it is obvious where their benefit money goes.
It is all about living within your means and doing the best with what you have. Laziness and ignorance are not about where you come from or how much money you have.
