There are a number of potential issues with self-service tills - they differ from one store to another, can be temperamental and the queuing system isn't always obvious.
Consistent with social loafing theory, our analysis shows that patients were treated and discharged at a faster rate in the dedicated queuing system than in the pooled queuing system.
The benefits of a dedicated queuing system may be due to greater visibility into one's workload and the increased ability for physicians to manage patient flow.
