I once got food delivered to a work site and it took like 15 minutes of go the last mile. Slowly walking all the way up the entrance drive to this place (it was a museum on the waterfront with like 1/2 mile of driveway before the parking lot) turns or he blew a tire and decided to walk it the last mile because he was almost there.
I felt so bad. He should've just looked after himself... I'm guessing the app would've punished him with a suspension or something if he failed to deliver though. Wanted to tip more after all that, but there was no option to posthumously raise the tip in app and I wasn't carrying cash.
Guess that's what happens when your boss is a robot.
