My local Meijer has 30 unused lines maybe only one or two being staffed. The two self checkout stations each have 20+ stations but they use the single line system which seems to always have 10+ people waiting. The line does move quickly. Then they have 3 super-quick self checkouts. These are labeled 5 items or less and don't include any shelf (direct into a single bag) and no weighing functionality (provided by a nearby machine that prints a barcode you scan).
