Almost every time I fill up with Gas, I test myself.
I start filling as fast as possible, and only let go of the handle once I've hit my total. My Goal? The Perfect Pump.
$20? Go all out and try to stop on $20.00 - no .01, no .06, it has to be perfect. Try it - it's harder than it looks. (Especially with gas at $1.04/litre.)
Tonight I did it. And nobody was there to witness this spectacular event.
There's always next time.
