Do you remember getting milk delivered to your door?
I was born in Philly in the mid 50's, and every other day we have milk delivered to our door, from Breuingers.
Every morning in the 1950s, like clockwork, the milkman would deliver bottles and jugs filled to the brim with milk.
If you were lucky, sometimes he would even deliver other kitchen essentials like eggs and butter. With the rise of home refrigeration the milk stayed, but the profession expired. Maybe if they delivered cookies too, milkmen would've had a better chance?
