Ray we grew around the same time 50's and 60's. Around here the only thing that was ever delivered was the mail and daily paper if you got one. As far as cold drinks you would be asked if you wanted a cold drink or Coke that was what ever thing was called no matter the brand.
We had and still have orange, grape, root beer. But the best one when i was growing up was a chocolate drink in a bottle that you had to shake up before you drank it it ( and it wasn't a Yahoo ) but i can't remember the name. We had small Coke's 6 ounce bottle and Big Coke's 10 ounce bottle. The little ones cost 5 cents and a big one was 7 cents and went up to 10 cents.
