It's all about scale, isn't it? One little doorway, up to which one truck can back and have its cargo unloaded one box at a time. Looming in the background, 2 cranes that can each lift an entire truck, literally, full of goods into (or out of) a ship's hold in minutes. Isn't modern technology wonderful? Probably depends on which end of it you're on. That "scale" thing again.
