Where did you come from? I am a man, and for 2000 I will buy meat, vegetables, which I have enough for the first, second and salad. Not for one day. On smoothies and tofu, I agree not enough.

Not everyone can afford to go to the store every day - then work, then work, in general, every hernia has.
So yes, 2K will be small for one trip.
