That reminds me when my car overheated near Halstead and 95th in Chicago. I got out to open the hood, and soon 20 people from the hood gathered around me. I always carried a gallon jug of Chicago water from my work place cuz water in burbs was bad. I quickly poured the cold water into the radiator and drove off to a gas station at Western & Kedzie. They installed a new V-belt and I was on my way home. Remember the good old days when many gas stations actually had a mechanic on hand?
My wife and I were a couple of 19 y/o kids from Ohio who moved to LA/Hollywood. I remember buying gas for 25 cents a gallon at a Philips 76 - the station with the big orange ball.
And on top of that, they gave away “Trading Stamps” as an incentive - sometime double stamps - to trade in on gifts and other junk..
