other couriers can afford to do it that way.

How do couriers recieve the mail?? they have them delivered by other couriers from one catchment area to another

Royal mail doesnt need to do this though.

Im not defending the postied 100%, dont get me wrong, of course you get the odd half wit thats shy of work.

Royal mail dont have the outlay to buy more vans or hire more staff.

It would be easy to send every posty out in a van but unfort its not the way.
