Ahhh, but was your sister's address correct?
I ask because misdelivery seems to be de rigueur in my cul-de-sac; my neighbour is frequently having stuff addressed to him posted through my letterbox.
Worst one was a guy further up: last week, he knocked and asked if I'd signed for anything of his (I hadn't; time of signing was when I was at Screwfix
Worst for three reasons:
- RM could tell him, to the minute, when it was signed for (albeit only a squiggle, so no clue who);
- RM couldn't tell him the address at which it had been signed for - that hadn't been recorded - only that someone in the cul-de-sac had done so;
- it was the bloke's wife's death certificate.
