But you can have multiple lines running at once. McDonald's already does this at busy locations. I find it dubious to say that they get your order out more efficiently. For one, having a massive line is a potential sign of inefficiency. Also, there's no technical reason I can see why asking your name from a second person to order your queue would be faster than handling this through an automated system. People like to say they get you through fast, but I personally have experienced long "absolute" wait times, even if it seems like the line is going quickly, to the point of I rarely like to go there unless I have time to kill. This almost never happens to the same extent in a McDonald's line, which is shorter, maybe slower moving at times, but lower total wait times.
