Back in the seventies I worked at a local gas station pumping gas also changing and repairing tires.
When gas went over $1
The pumps we had did have a setting for over $.99 9/10th. When price went over that set price to half and pump half as much or twice as much to get the right amount of gas for the price. I just got a headache trying to remember which it was.
There was gas rationing with odd and even days off your license plate and lines down the street. Minimum wage was only about $3.00
I worked so many hours there that I said the name of the business when I picked up the phone at home.
