This morning I delivered a sack truck load of reams of paper and other non-specific boxes of stuff from a medical supply company to the GP surgery at the end of the road.
Someone somewhere had been using handwriting for critical data[0], and 'A' had been parsed as '4'[1] when entering the address on the shipping label, causing the UPS driver to ignore all the obvious clues[3][4] and attempt to deliver it to our neighbours. Who weren't in.
And this evening I had to explain to our confused neighbour why I no longer had the mystery parcel that UPS had left him a card for.
[0] ETA: With hindsight, this is the NHS, so I've no idea why I thought this was in any way remarkable.
[1] This is a new one for us, as we usually get the ones[2] where 'a' has been parsed as '2'.
[2] Usually hand-addressed envelopes containing confidential medical data, rather than parcels of office supplies.
[3] Full name of the surgery on the address label, big building with matching name in big friendly letters on it across the road, name of medical supply company on the boxes, that sort of thing.
[4] To be fair, barakta missed all this too, when she signed for the delivery.
