(title due for delivery on the 31st November)
"You would get away with it once. The second and subsequent times it would be rather obvious that the [missing items] were following you and you would have some explaining to do.[...] That's if you still had a job [delivering parcels], of course."
Yodel (and companies offering a similar customer experience: Hermes, and DPD Local (formerly Interlink Express), and ...) still exist, don't they?
Is any more evidence needed to prove that your theory doesn't match the real world ?
If sellers who use these delivery companies made it obvious up front who would be responsible for delivering the goods, then customers would be able to make *informed* decisions on where to buy, and many might choose to shop elsewhere and/or pay a little more for a reliable delivery.
That way, underperforming delivery companies would fail, if they didn't improve.
Isn't that the way competitive markets are alleged to work?
