The wife it seems nearly always wants something changed, or added, or finagled. I can't quite convince her this results in mangled orders. She'll order an egg white McMuffin, but then with cheese, and sauce on the side, and no potatoes, but a Coke, and no bacon. Or something. With a French accent through a mask.
In France, you order with a flat panel kiosk thingee so you can do that. In the US, the trainee cashier who started working an hour before gets it all mangled every time. She ends up with a quarter pounder and fries and can't understand why.
