The local taco bell's drive thru is at a downward slope. So I cut the car off, stick it in neutral and let it roll. Might have to open the door and give it a little kick so that you can start rolling, depending on your drive thru. I've gotten to the area of the parking lot where you get ready to get back onto the main road with my car off. Then of course I'd have to turn it back on and drive home.

Because of this eco-friendly drive thru (they didn't intend for it to be so, of course) I probably save fuel versus parking reversing out of the spot etc.
