I don't believe that either of these concerns are the reasons for the no pedestrian policy. It may be what you
hear from the person at the window, or even some in management, but I think the person at the window doesn't know the reason any more than a random drive-through customer, and if the manager does know he's probably lying.
The reason for the policy is that cars have license plates, which make it easier to identify you in case you do rob the place, or drive-off without paying.
