The McDonald's nearest us not only has and uses (I haven't used it myself but I've seen it used) both windows for that purposes but also has two drive-thru ordering lanes that then merge into one before the windows.

I've wondered how they make sure that the cars stay in the correct order.

None of the other fast food places around here (including the other McDonald's) even has a second window to not use.
