unsure whether they are adopting post office queueing or not

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

Single queue, multiple server.

Although ironically the Post Office used to have separate windows (and
separate queues) for different activities. So you'd queue once to buy
stamps and then again to renew your car tax.

The muddle tends to arise when a multiple server multiple queue
situation (eg the default at most fast food outlets) gets overloaded,
and people form an additional single queue, where customers peel off the
front to join the each server's queue when the latter get down to about
two or three per server.
