Fill'er up

Sorta knocking an idea around in my head. Pick a fast food place, most any will work. The craze today seems to be the "Drive Thru Window". So just imagine this, order your food, wait, drive to the window the cashier (should be a pretty female) gets your food and politely asks "Can I get you a fill up of mid octane with your meal?" Install and maintain a gas pump, and get this, you only need one more employee to pump the gas while the car is at the window... welcome back to the full service gas station. 

I amaze myself at times.
