Find a car in the line, explain the situation. Ask it they'll be your proxy and buy your order for you. Hand them your $10.00 bill (or whatever). These joints often get multiple orders for one car that are packed and charges separately, so it should be smooth as silk.

I'm sure, that with some gentle cajoling, most crews at these joints would serve a cyclist regardless of the rules. Especially if they see that you'll be eating anyway, and it's easier than having them look bad putting you through the workaround.
