A Five Degree Difference in Expansion?

I wonder if these people ever consulted either a chemical enginner or a physicist before they file this lawsuit. It seems that a class action lawsuit has been filed against several Florida gas stations. It stems from the fact that when these gas station buys gas wholesale, they pay for it and the taxes when it is being sold at 60 degrees (Fahrenheit). But when the gas is sold to the customer, the fuel is kept at, get this, 65 freaking degrees!!

The suit against Murphy Oil USA, Marathon Oil, 7-Eleven and five other companies claims the defendants have ''exploited physics'' by paying fuel taxes on wholesale gasoline stored at the industry standard 60 degrees, then selling it to customers after it expands in underground tanks that typically generate temperatures of 65 degrees.

Someone call the President and complain!

Now, I'm no expert in the properties of ordinary gasoline. However, I simply cannot imagine that a temperature difference of 5 degrees Fahrenheit (which is considerably smaller than a change of 5 degree Celsius), would make THAT much of a difference in the gasoline's density. In fact, I would think that the inaccuracy of the pump kiosk itself has a bigger impact on the amount of gas you get rather than a mere change in the gas density by a puny 5 degrees.

I honestly am constantly amused at how some people arrive at the decisions that they make.
