When I first bought my larger family house in Brighton back in about 1985, we had milk delivered every morning. The children were still at school and required copious amounts of milk for their morning cereals, etc.
The milkman drove one of those electric milk-floats which were mostly silent other than the sound of rattling milk bottles in the metal crates. Milkmen, in those days, were all called 'Ernie'.
He arrived at our house at exactly the same time each morning. I had no need for a bedside clock; the milkman served as one. I got up as soon as he'd been by, which gave me time to do all that was necessary before trying to get the kids out of bed, washed, dressed, and fed.
I had imagined that daily deliveries of milk in glass bottles had finished, but I was pleased to see the above recently. Some traditions may not be used by all, but the expression 'use it or lose it' is very apt in the case of Milkmen.
If a Milkman passes your front door, get him/her to deliver daily. It not only keeps a tradition alive, but it is far more convenient than rushing off to the corner shop (in dressing-gown and slippers) for a pint of semi-skimmed in a tetra pack.
