Well, out in the sticks we must be luckier. Because my daughter( who doesn’t even live here) gets tens of parcels a day some days ( competitors products that she wants to examine, but obviously doesn’t want to use her company address). All the delivery people seem to be great. Many we know by name. The post person , and regular deliverers, know where to leave stuff, and hide stuff imaginatively in one of the places.
They know that they are always welcome to park in our drive, and to use our loo. Obviously we show our appreciation to them generously at Christmas. In short, building the relationship works - but I guess it’s harder in areas where more people work the patch.
