It is noon in Perth, Western Australia. And 45º C out in the open. 113 F. Drivers for Fasta, Star Track, DHL, Australia Post, and a number of other courier companies are out there dressed in overalls and fluoro vests calling at suburban addresses delivering the things that people ordered on line. All day.
If you ordered something yesterday that will arrive today, have a cold can of soft drink ready for the driver. He is a Christmas hero.
