How will the Post Office cope with the grantee influx?

Sir
It is with great consternation that I write this open letter to the Courier.
I had the misfortune of having to collect a parcel from the Post Office today.
I arrived at 11.25am and stood in what seemed to be a relatively short queue of five people, which managed to grow to seven because some claimed to have had places kept for them.
There were supposedly two tellers available, one was not helping the queue but seemed to be assisting random people not in the queue.
Maybe we should call it one and a half tellers as the one seemed to need assistance from the other.
I stood there till 11.47am when I gave up, as only one person who was at the teller, when I arrived had left the Post office. The following old lady, in the queue, had spent at least 15 minutes in front of the window when I decided to leave.
My question is:
How do these people think they will even remotely be able to cope with the influx of pensioners looking for their pension payouts when they supposedly take over this function?
This is a place with no supervision, no direction and certainly no customer service.

This letter was sent to the Post Office’s Communication Department for a response but up until the time of going to press, none had been received.
