I never thought of it that way. Its a shame that the cost of groceries can be significant in some parts of the world. In Asia, a meal(very good meal) can be delivered via a hawker at the price of only 2£. Many of our food stores also open 24 hours, unlike the UK.
I got so accustomed to cheap food that I never bothered to consider groceries as 'cost'. Its just like penny change. Why is food in western countries so damn expensive anyway?
Yeah this is the cool thing about Asia. Ok, one of the cool things anyway.
