> Under the Landsburg system, the stalls still serve one seasonal treat a minute, but the queues are short. Alas, the Landsburg rule can only be imposed in controlled environments such as a theme park, perhaps.

Poor example. This would annoy the hell out of customers. Theme parks also almost always have excess demands for rides. This system would only work at a failing theme park that couldn't fill up the ride to capacity.

I could imagine this working with decentralized robots performing similar tasks independently, but usually a system that uses robots would be centralized.
