It just seems like more work. The amount of time buying ingredients, cooking the ingredients, washing up after cooking in order to eat a meal seems out of wack to me. So I always end up cooking more for myself than I should because ultimately I'm sitting there thinking "there's no point going to all this effort for a tiny amount of food".

But realistically that's not what happens, I just end up buying a lot of store sandwhiches and takeaways instead.

Cooking to me seems like a hobby some people really enjoy or at least competent at, if you've got no interest in that hobby then it's easier to just swap money for food directly instead.
