1. My driver "took the wrong turn" and showed up 15 minutes late.
2. The amount I tip depends on how good the service was, and a driver who shows up 5 minutes early deserves a better tip than someone who is late.
3. I watched him in the app (I was hungry!) and he took at least 3 wrong turns.
4. It normally takes 15 minutes in this traffic but he took 30.
5. App forces you to choose how much to tip the driver before your food is delivered.
