It’s not stealing really, because you can report it for a refund, and the refunds on those apps happen pretty quickly. It would be annoying, but you would get your money back. Your money is basically in escrow until a while after you get your food, so you can also get refunded if your order is messed up. The driver doesn’t even really get in trouble unless they mess up often, they just don’t get the fare for that trip.

I mean it’s still a shitty thing to do, but it’s more like getting bad service than stealing. The same outcome would happen if your drivers vehicle broke down, for instance.
