Sadly true.

In theory, you could move both the ordering and payment processing into an app, so there's only a pickup window. That'd let the no-attention-span ditherers take their 15 minutes to order without holding anyone else up. Obvious downsides - electric bill at the AI DC, barrier to new/occasional customers (app required), and the C-suite probably loves holding customers mentally "hostage" in the drive-through line.
