Heh, I've thought of this question as well. The In n Out by my place has two drive thru lines, one on the north driveway and one on the east driveway. I used to size up the drive through line on north, and if it was too packed, i'd go through the east driveway and park to go up and order. While I got my food relatively quick, I was then blocked in by the drive thru cars. Nowadays I just wait in the drive thru line in the east driveway because it's quicker, or park a block away and walk (if I am not in a rush)
