Yes, obviously the courier was unable to press a doorbell button or knock on a door because he had no limbs. What happened to the recycle bin where you told us a day before the guy stashed your goods?
Here we go again .... "answer the call!!!", "answer the phone!", "answer this call!", "Don't block", "DO ANSWER!!!" ..... Does the phrase "broken record" still mean anything to you?
What is the penalty if I don't answer? Hmm? What's the worst that can happen? Just maybe there is something going on in my life at that moment which is far more pressing to me than some schmuck tooling around outside with a cardboard box burning holes in his palms.
Or maybe I find it ridiculous that a person who is hired to locate and visit strange addresses all day can't find his own rectum with a flashlight and a mountain sherpa unless he calls me several times from an unidentified phone number. This is supposed to be for my convenience?
You really want me to believe that a courier making nine to twelve stops an hour has nothing but time to call every one of his same-day consignees because he can't find "north" on a map? Or he needs to proudly announce his clever hiding place for a parcel? Or consignees immediately fall dead asleep or develop amnesia six seconds after ordering and therefore cannot watch for the courier's arrival?
If these stringer drivers cannot think on their feet and solve their little problems without someone else wiping the mess, they have the wrong job. But let's underline where I'm going. None of these specious excuses for the mystery phone calls aligns with my experience of doing the same job for a different company. While physically exhausting, the vast majority of stops are simply not so difficult to manage in a logistic sense. You would think from this thread that Prime drivers need to pause and question and hesitate all day, and maybe would find air traffic control or nuclear power plant management less complex work for better money.
As others have noted, this is Amazon. The first time I met an actual Amazon delivery person, he explained that they would often call if no one answers the door because they're trying to prevent packages being stolen while sitting outside the door. He also said the calls would usually show up as a Seattle or Washington, DC, number with no other identifier and wanted me to know it could be him trying to call.
