I am ornery though. I just chucked an egg McMuffin at the store manager's head because they forgot to put egg on it. They gave me a totally free new order, and a little card for a free McMuffin.
This is Florida though. I could rip down the drivethru speakerphone and just be considered average as far as bad customers go!
