When I was a kid, we had a big family, and the milk-man would bring a whole milk crate from his truck. He would shout “milk delivery,” walk straight into the house without knocking, go into the kitchen, and put it in the refrigerator.
Often we kids would be eating breakfast. We would say “Hi Mr. Riley!” and he would greet us, comment on the weather, and be on his way.
We didn’t find the whole thing strange at all.

Pretty much the same. Mom had 5 boys. We had milk delivered twice a week IIRC. If the front door was open he’d knock, announce himself, and walk in.
This would have been the mid to late 1960s. We thought nothing of it.
