Why do gas stations charge an extra 9/10¢ per gallon of gas on top the > 4 dollars per gallon?
Back in the olden days when I was a kid and gas price was around 30¢ per gallon and a penny had significant value I could see a reason for the 9/10. Perhaps the 9/10¢ per pallon encouraged drivers to buy at lease 10 gallons of gas to save a penny?
But nowadays when the price of gas $4.00 9/10, and the value of a penny in so low, it is not even worth considering the 9/10.
Do you know why the oil companies continue with this insignificant and archaic pricing?
