Mission 2: Cash-flow constraint
Lower available cash to £250. What order size can the café afford without going negative?
Mission 3: Safety buffer test
Try zero safety stock, then three days. Which setting gives more risk, and which traps more cash?
Mission 4: Language service
Practise one phrase for telling a traveller that a fresh batch is arriving soon.
