My unusual story

I was traveling down a road. somewhere USA, and came across a very old service station, antique with old billboards to advertise, coca cola, tire &oil changes, gas for , am I seeing things?, 39 cents a gallon, I did stop cause I was curious.
Stepping into the store/station sent me back to older times,. a newspaper said on the headlines 1936. wow! a glass case on the counter with different baked goods, and on the walls, baking powder,and other things of that era.,on the floor were barrels filled with different things, nails in a barrel, hey! pickles in vinegar in a barrel. There were farming equipment too.
Did I go through a time tunnel or something? An old guy came through the door, in bib overalls, wiping his hands on one of those old red handkerchiefs. He asked me what I needed in his country drawl.
I did need gas so I asked him if he would fill it up. He responded , "sure thing." while waiting I got me a bottle Coke, so cold! and so good! what amazed me so, he couldn't find the opening for the gas, and when I opened the hood, he was so startled, like he never seen a car like that, why is the battery there and not under the seat? he asked after he filled my car for $4.00 I left, going on my way. what happened there? did I cross over or something? well I was curious I turned my car around went back the way I came, and y'know I didn't find that old store/gas station. and all I have is an empty coke bottle!! the other thing maybe I dreampt it. Next?
