TheMailman?
Mail is not delivered to individual houses here but is posted into boxes around the area. This is a small bank of boxes, "ours" has more stands of boxes, I think about 7, so handles the mail for a lot more houses. It means that you have to get yourself to the boxes to collect  your mail. By the look of the tyre tracks at each set of boxes, most people must stop off on the way past in the car, but I wonder about those who don't drive of are ill or just frail or elderly, it must be quite a chore just to collect the mail. Our set of boxes are over 2 blocks away and when there is a lot of snow or the footpaths (if there is a footpath and that's not the case  here in Water Street) are very icy, it often means the mail might go uncollected  for days if at all. I can imagine it also gets a little busy at times with a number of cars  all arriving at once, which I imagine would make it quite unsafe.
