re: 1st world problem of the day. Chick Fil A drive thru etiquette.

Our Chick fil a is different.

First, why would I be paying attention to people in the other lane and the second that they are done ordering?
Our Chick fill has the order taker walk down the line (essentially taking 3 orders at once... not just the front of the queue).

Second, our Chick fil a has an attendant after the order to get everyone's names to assist in the delivery window where they run food to 3 cars a time.

It is essentially a zipper at the front. But if the lead car is stalled, no one is waiting for the zipper. Chick fil a confirms the order immediately after.
