All Food Disappears from Bento Box & Pockets

Recently, I went to a restaurant and they gave me a box with food in it which I stuffed full with food to maximum weight, but today when I flew in the box was empty all together and I know for a fact that I didn't eat all that food in my sleep.

Can you please help me get all that food back...? I am a poor law school student and had grinded for ours to get the fund for it.

Thanks in advance,
