Well, I never considered myself older then dirt but I guess I am getting there. I remember a lot of these things too, especially milk delivery. I remember my mom putting the note in the top of an empty milk bottle with what she wanted delivered and licking the heavy cream from the bottom of the bottle stopper.
Our fast food treat was A&W drive in. I remember they had the burgers named Papa burger (a double patty with the works) Mama burger, brother burger and sister burger. We ate in the car with that little tray thingy the carhop stuck on the window. Wow.
