ON October 4, soon after 9 am, a letter of mine was weighed and the postage for air mail express to Perth, Australia, was paid with the letter being placed in the ''express'' white box.
It did not arrive at its destination until October 19 - 15 days later.
Even ordinary, non-express air mail letters should arrive faster than that.
Such incredible ''efficiency'' is surely mind-boggling.
