At Mây, a tiny sticky-rice stall on Lý Thường Kiệt Street in Hanoi, office workers and students routinely queue. A few square metres of pavement hold plastic stools and the rice baskets, while the stall can sell about 1,000 portions a day from 10,000 dong. Customers even film the proprietor slicing mung bean “like a machine.”
This line exists not because service is slow, but because demand can exceed even very fast hands. Without a permanent dining room and serving mostly takeaway customers, the stall pushes manual work to high speed to feed the city's morning. The queue is less a sign of inefficiency than a dense business fitted into a few metres of pavement.
