I had a van full of kids, and asked at the drive-up if they had enough double cheeseburgers to fill my order. "We'll have them by the time you get to the window".
At the window, I was told to pull over and wait. I turned off the van and sat. "I'm not moving- you said my order would be waiting for me".
Five minutes later the traffic was piled up behind me. Manager comes to window and asks what's the problem. Employee said "this is the guy that won't pull over". She gave me a dirty look and walked off. Got the food and left.
People like you piss everyone else off. The drive through is supposed to be for quick orders on the run. Not for people like you who are just too god damned lazy to get out of their car and walk because you might actually have to *watch* the kids you're with.
Or, you could go one step further be a little more polite, and CALL your order in if it's going to be that obnoxious, instead of being a complete dick due to your own incompetence.
