what is meant by "post office queueing" in this context?

The Royal Mail has undertaken a redesign of its branches.

Only some of its branches, as I've not seen this in any of them.

Instead of queuing in a line, you take a number from a machine for the
type of service that you require and approach a counter when your
number is called.

At least I think that's what it means.

I'd call that delicatessen queuing.
