Gasoline that is. LOL! Have you noticed that practically every other day TMZ and sites like it are posting pictures of Britney Spears getting gas. Who needs to fill their tank every other day? She can't possibly be driving that much. She can't possibly go thru that much gas just driving around to fast food drive-thru windows every day.
This leads me to believe that she is just going to these places for attention OR she has a crush on the gas station worker.
