Priya manages inventory at a Bangalore medical supplies warehouse. Every morning, she receives a list of 50 items to pack for hospital deliveries. She picks items in the exact order they appear on the list — Item 1 from Aisle A, Item 2 from Aisle M, Item 3 from Aisle B, back to Aisle A for Item 4. Her colleague Karthik suggests she could save 2 hours by grouping all Aisle A items together, then all Aisle B items, regardless of list order. Priya refuses because the hospital's system expects items scanned in the exact sequence printed.
