So the refrigerator is chock full of food, but I'm not quite sure what I bought, and I'm afraid of eating other people's food. How do you deal with this?

I am not sure if a guff/ng system is the right one. Does labeling something guff imply pressure to do the same? Keep in mind that some members of our household eat out much more than others, so inevitably end up buying little for the house.

I am also worried about a tragedy of the commons situation, but less for me. I think I am worried about taking advantage of other people's coerced generosity.

In the meanwhile, I need to go find some food.
