@Fizzfizzpopop @Bez_Lightyear Yeah, you do tend to get out of the way of people who come out of their houses and follow you. You never know what they have in mind, best to be safe.
Part of the personal safety training is not to be trapped in a dead end by anyone coming out of their door after you, eg when you're in a corridor in a block of flats you start delivering from the far end and work you way back towards the stairs, so you've always got an escape route.
Another part of the training is "all death threats go to the police, it's their job, not yours, to decide how serious they are". I personally have never bothered, though I did once check with the council about a tenant. (This is *not* a recommendation - follow your training.)
