Short-Changed At The Drive-Thru

So I went to McDonald's with my son to get dinner last night. After ordering, I pull up to the "First Window" to pay.

"$8.83 please", says the girl.

I hand her a fifty. And she gives me change. I put the car in drive and start to stuff the change in my pocket, but notice that I was short-changed by $1. I'm already in motion, so I can't back up. So I pull up to the "Next Window". A handful of bags gets shoved in my face.

As this oriental girl hands me my drinks, I say "Um, I think I was overcharged by $1, can you tell me the cost of my meal?"

She says, "meeoo no come wit meeook".

"No, how much was my MEAL?", I ask.

"You no get meeook", she says.

"Forget it", I say.
