Might add in late 60s a tank of gas was $5.00. Two 4s, 5.86 gears, cruising Friday and Saturday nite would take 2 tanks. Didn't matter back then, $100 or more does today on wall mart greeters salary.
In the year 1967, the average retail price of gas in the U.S. was $0.33.
This is equivalent to $2.47 in 2018 dollars. National Average Price of gas as of 8/20/18. $2.838. It's $2.69 around here.
Lol , In the early 70's I absolutely refused to buy Sunoco 260 because it was an outrageous 45 cents per gallon.
Typical Walmart greeter probably does not use 2 tanks of gas in a month.
