Traditionally, the Chef had to wait for the elevator themselves. Now, they just throw a request down a **[[Workloads/IO/AIO/_Aio|Pneumatic Tube (AIO)]]** and these specialists catch it. This wait event indicates the worker is standing ready at the bottom of the tube, waiting for the Chef to send a new request.
