It's much closer to a restaurant supply store that happens to be open to normal people.

If I want to make tacos tonight, and I try to shop for that at Costco, I'm making tacos for a week or more. There's no small size of anything, which is the entire point.

I cannot fathom the people who do weekly or so grocery shopping there. How can you possibly plan out a months worth of pantry for a family like that? It's a skill I certainly don't have but families did for millennia when running small farms and such. Maybe the Navy could teach me how.
