I was under the impression that OR engineers are supposed to wear PPE when visiting a customers house?
I noticed an OR van driving up the road and naturally I had a peek out of the curtains to see if he was stopping around here. He got out of the van, wore a blank high vis vest and walked up to the door way of a neighbour on the other side of the road. He didn't go in, and from what I can tell the work seems to be were the phone line (served by a telegraph pole) comes down from the side of the house to near the door way. So the work is just outside the front door. I was just surprised he had no PPE on.
