I was a gas station attendant when I was 16 and 17, so...1971 - 72, full time in summer and part time during school.
In the summer of '71, we had a classic "Gas War", when gas stations gradually lowered their prices a penny or two less than the next nearest station.
After the station nearest ours changed their sign from .14/gal to .12/gal, we posted ours at .11/gal.
Eleven cents for a gallon of gas (regular octane) in a small Central California town in the summer of '71.
We didn't get any busier than we did all the previous summers, and the average local still said "Gimme $2 worth o' regular." Sure, they got a fuller tank for their 2 bucks, but only 2 or 3 people per day rolled down their window and said "Fill 'er up!"
It was funny watching the station owner watch the other station's sign, biting his nails until they finally posted their normal price of 24 cents for a gallon of regular.
Just a month later the price went up to .27, and by Christmas that year, regular gas was going for .34/gal.
When I worked my last day in 1972, people were yelling at me: "42 cents! ....for regular??"
It was highway robbery!
