At busy Taiwanese night-market stalls, customers may queue to order, receive a number and then wait beside the pickup area while the food is prepared. Taipei night-market guidance likewise notes that popular stalls may require visitors to take a number or join a queue.
The line to order and the wait for cooking take different forms. Once the body leaves the line, a paper or called number carries the turn forward, preserving order while freeing a narrow market walkway.
