I was not even talking about those who knock and leave, but those who never come and lie about attempted delivery.
The shipper paid UPS to do a job (and the money really comes from the consumer). The consumer paid for delivery on the promised date, and for three real attempts, not two, not one. Thus fake attempts are also indirect theft.
There should be no sympathy for liars and thieves, or those who defend liars and thieves. If they lie and steal and do not do their jobs, they deserve to be underpaid -- in fact, they are overpaid.
Sometimes the product is not a phone but medication, although it is not up to UPS or the driver to judge what is important.
That said, I admit that it is hard work, probably unpleasant. But lying to get out of work that the customer has paid for should not be a legitimate option.
