As previously stated, for the PoA to be valid, the driver must know of the waiting time before the period of time commences starts, but the driver does not need to be notified specifically. It is enough to know about the waiting time, and its duration, in advance, and therefore the knowledge could be by:
being told
arriving early for a timed delivery
always experiencing a wait at a specific location.
I have always understood it to include the last sentence when using POA.
If you know from experience of a wait time then you can also book POA. As you work there and wait on a daily basis I’d book it as POA as you know frequently how long you are likely to be waiting from experience.
