Had a moment earlier this week that really vexed me. I called at a property, delivered the post in a box on the wall, about half way back down the path which is obscured by view from the house you can hear owner open the doors and the sound of rampaging dogs being let loose now chasing after me.
Honestly, no respect shown, clearly they've gone to get the post from the box, but haven't bothered to keep the dogs inside, is it too difficult to wait a minute or two until the postman has left?
And again today, called at a different property with a parcel, no answer, walk back towards the gate where the box is, before I get there I'm being chased by two dogs because the owner has now come to the door.

I don't want this to happen again because the dogs were actually quite agressive, there's no means of alerting the owners from where the box is on the gate, so can I just 739 anything in future?
