Oh, one other interesting thing I've heard happens regularly. Couriers have multiple cellular devices. The second account usually get batched orders from the same restaurant they are already at which leads to a host of problems for the customer and restaurant. This leads to the order that was ready first to just sit and die in the courier bag while they work to maximize their earnings. Couriers sometimes leave before the second-order is ready and return well AFTER it's been ready to retrieve it because they are out and about delivering other orders.
