Is "handed to resident" some sort of euphemism? Because it wasn't handed to me, nor is it in the hall or outside the door to the flats.
Anyway, sometime later I headed out for a stroll and happened to glance over at the neighbouring flats. And outside their side gate... was my Amazon parcel.
Sadly Amazon's how-was-your-delivery feedback doesn't have a "you left it outside the wrong house in plain sight on a busy footpath" option.
