What were gas stations like when you were young? How much was gas?

Now, I only know about the gas stations in the town I lived in so they might have been different in other parts of the country.  If you have ever watched the Andy Griffith show when they had a segment that included Gomer or Goober and their gas station, that is how I remember the gas stations.  We could go there and get air in our bike tires or buy a soda from the machine that sat outside the building.  Dad would go for gas and an attendant would come out and fill the tank, wash the windshield, check the tire pressure and check the oil without being asked.  He would usually have a smile too.  It was a friendlier place then.  The station only sold, other than soda, things that pertained to the automobile or bicycle.  They repaired cars too.  You didn't have to go to a different place to get your car worked on, as they would say.  The place always smelled of oil and grease and the people who worked there had smudges of oil and dirt on their clothes.  Hands and nails were dirty too.  Amazingly, they didn't charge for air or water.
I don't remember the cost of gas when I was young because I didn't have to pay for it.  The first price is remember is from the sixties when it was thirty five cents a gallon.  I was only making  a dollar an hour so comparatively it wasn't cheap.  Another difference was gas was purchased by the gallon not the dollar amount.  Now, we go in and ask for twenty dollars worth not the eight gallons we used to and we have to pump it ourself.  Not a good change.
