To contrast, there are a group of McDonald's stores near my office that are testing a linked drive-thru timing application. There's a scoreboard visible from inside the work area that ranks all the local stores in terms of drive-thru speed and service time. They've gamified the system.
There is a BK near the office, and I used to attempt a drive-thru on my lunch -- but, their drive-thru was actually slower than going inside. After a few attempts (and being late back to the office once) I gave up.
