Quirm Royal Post Office
During the glory days of the Royal Ankh-Morpork Post Office, a branch was also based in the city state of Quirm.
Due to a miscommunication in the twilight years of the Ankh-Morpork monarchy, the king issuing an order with his mouth full, Quirm's branch of the Royal Post Office once employed trained ostriches as delivery staff. It is unclear if this practice has resumed as part of the Post's current revival.
