Here here. Couldn't agree more with 'why shouldn't you if you can?' If you can spend £30 a week on rank student nights getting ratted why only £5 on food.
I'm the first to admit my budget is different to most but still:
student loan is like £3k isnt it?
student term is how many weeks? I dont do maths, but that should mean you can spend more than £5 a week on food. In london £5 gets you a pack of crisps, sandwich and drink with one random item in the union.
If you get a part time job in the union behind the bar that means free drinks + if you're shifty/sly extra money from short changing.
Making money is easy if you want to and eating is such a great pleasure in life that it's worth every penny. Its like women like spa days and shopping. I like going to a nice supermarket/ department store in London and buying some top quality ingredients and always feel satisfied. My wardrobe however, has suffered because of said indulgence.
Student overdraft + student loan= enough to spend sufficiently on your wellbeing and happiness: both of which are directly effected by what you eat. Plus if you eat well you wont get spots or look like a typical geek as such, your health is more important than the other random carp you spend your cash on.
