Milkman. et al

When I was growing up, all kinds of products were delivered right to your door, by an assortment of  interesting characters.
I can still see our small aluminum colored milk box on our back porch, which held maybe 4-6 quarts of milk. We got delivery a few times a week and it was great going out there on a snowy morning and grabbing 2 quarts or more of fresh milk. Once in a great while, my parents would pop for a chocolate milk. I think you filled out an order slip each week, telling your milkman (ours was named Vic) what you needed for the next week.

The strangest thing we got delivered was bleach..or as my mom called it , "no worry". This couple would come by and take your empty bleach bottles right out of the cellar and replace them with several other gallons. What service!
There was the old fish guy too, who I was scared of, pushing his fish cart down the street yelling out : FISH! Although we never bought from this guy, he would occasionally fill his water bucket from our outside hose line, which still irks me for some reason to this day.
For a while we had an egg guy making the rounds and of course the more corporate Charles Chips vehicle, who delivered snacks to the doors of the more affluent.

Other scarier door to door types came by regularly, like this poor guy who walked in a very slow, crippled sort of way. He wore a suit, carried a valise, and I think sold fabric and ribbons. I was terrified of this guy and would only watch him from a distance.

To round out the excitement that always seemed to be swirling around our neighborhood, was Kenny, the delivery guy from the mini supermarket . He would deliver the groceries you bought right to your house, in a shopping cart,
all the while loudly singing such  favorites as "School Days" . His melodies were tailored to the seasons.  His philosophy included such spoken gems as "nice day, too bad it's raining" He suffered from some mental disability and was a little scary, but in the end, harmless.

Looking back on things, childhood life in this regard was damn  interesting.
