That would seem to make the chance for an angry confrontation and possible injury much greater than if he had simply been handed the Big Mac he ordered.

If worker safety were the issue, then it should be provided by improved physical security in the window design. But the current policy does nothing to keep potential criminals away from the window nor does it protect the workers from them. The only effect it has is to turn away legitimate customers who just want to receive the food they ordered and are willing to pay for.
