I was thinking about this yesterday (but not about the size of people’s TVs).
The budget you have for food depends on what other things you spend money on. For example, if you are a regular smoker, drinker, drive a car, or have a big telly there is bound to be less money for other things, like food.
We are not poor, as luckily we are both still working, but we don’t smoke, drink (a lot), drive or have a big telly. To us, good food is worth spending money on. But we are vegetarians, grow our own vegetables (in summer), and cook “from scratch” [horrible expression emoticon]. Perhaps this one
