It's probably intuitive to most people that the gasoline in their fuel tank expands in the heat -- just like doorframes and cookware and everything else on the planet. What's probably less intuitive is that, in the United States, this physical phenomenon pumps a nearly $2 billion annual windfall out of consumers' pockets and into oil company coffers, according to numerous calculations, including a recent House of Representatives study.

Unless your gas station has above ground fuel tanks this isn't an issue. Underground fuel tanks are buried deep enough that they are relativly unaffected by changes in air temperature, except in extreme events.
Something that should be of more concern is the Vapor Reclaimation Systems that remove the evaporated gasoline from your tank and pump it back into the storage tank where it condenses.
The allowable error in the gas pump measurement system involves a far greater amount of gasoline than either of the two issues mentioned above.
