here's a trick to speed up the filling up process...you don't have to turn you engine off. you dumbasses probably think you do, but you don't. you're welcome.
Good TIP!
Here another helpful gas pumping H4XX0R:
After you select the cheapest gas, quickly press the cheap gas button once, the midgrade twice and finally the premium once. If you do this in under 15 sec, you will get premium gas for the cheapest price!
