In Western MA we had milk deliveries several times a week. When we went on long weekends my parents would often not tell the milkman. When we returned we'd have several quarts of sour milk. My mother would take them to the woman who lived behind us. She was from Poland and would give us one of the very rich chocolate cakes she'd make with that sour milk. YUM!
If I remember correctly, Mr. Archbault would periodically deliver laundry or dry cleaning.
When we moved to the suburbs a farmer would come around weekly to empty the in ground garbage pail beside the back door to feed his pigs. I wonder what happened to those pigs when we finally installed a garbage disposer.
