Tank lorries are used for liquids, refrigerator lorries for perishables, and vans for furniture and valuables.
Signs of a store in trouble: Stocking fewer perishable items, storing non-perishables in refrigerated cases to make them look full, and "dummying up" shelves with empty boxes.
This way, the deli-meat and other perishables you bought will have less chance of going bad, and your morning routine will be more consistent.
