It used to be that the majority of Americans had their milk delivered straight to their front doors. Every day, the milkman would place bottles of milk in a “milk chute” that had a small cabinet with a door on the outside.
As time went on though, sightings of the ever-famous milkman became far and few between. In fact, fast-forward to 2005 where only about 0.4% of consumers had their milk delivered to their front door, according to Wikipedia.
