Mama's maker says flood alerts sent at about 09:00 triggered a rush to buy. Pork and fresh vegetables sold out first, and convenience stores ran out before supermarkets. Big retailers hold about 2–3 days of stock in their system, and distribution centres about 3–4 days. Delivery to stores may be slow because small delivery trucks struggle in flooded areas. The company expects the disruption to last about 2–3 days, not a long shortage. For a shop owner: keep a few days of fast-moving goods on hand, plan for slower restocking, and expect small neighbourhood stores to run out first.
