<< Make random engine noises like *roar* *rattle* & *pop* while placing and paying for your order. When you pull up to the window, explain that you're driving a late model BMW, with invisible spraypaint finish. If all else fails, run around the parking lot and scream like a wild chimp on crack cocaine.
😕 eeek! eeek! >>
It might be more believable if you made buzzing sounds, attached a coffee can to your ass, and wore a backpack with a shopping cart handle on it. You'll pass as the new Civic.
