Well, imagine if you ordered in all the time - she had that expensive meal service. Then the kids are whining for food and youre too pissed or busy to feed them and so you order in. Afterwards you bin any leftovers because you can't be arsed to tupperware them and your giant american fridge is full of decomposing groceries and chaos.How can anyone spend $1000 a week on food?. They’d have to be dining out a bit.
Then you go to an expensive supermarket with no meal plan or shopping list - bonus points if youve had a few drinks and/or pills. You buy at random, expensive tasty things and include wines and spirits in the bill. On returning home you become distracted and fail to put it all away. It goes bad. Repeat cycle.
Ive never done this myself (I'm nearly in tears if I let 3 eggs go off ) but I can see how it could happen.
