Answer and Explanation:
Corruption is a vast word. It implies premeditated thought and action.
So in the food delivery service world, I don't think there is much room for it, but since you asked, the only way that the customer could participate in corruption is by simply not tipping. This just says that they are entitled, and they don't feel like paying for service, just like going to a restaurant, paying the bill, and simply not paying your server any tip. Another way they can contribute and dishonesty is by receiving the food, but then indicating to the delivery service that it was never received, in hopes of an additional delivery, or reimbursement. This would, however, possibly end the opportunity for the driver, or at the very least, have severe consequences. All dishonesty has an affect.
The delivery folks could really only contribute to corruption by eating, or stealing food or product from the deliveries. That would be premeditated but would be something that would be identified by the customer, which would typically open some sort of investigation.
Otherwise, we tend to look at the top of the food chain in being corrupt, whereas in reality, they are only guilty of having built a system of convenience that people are happily paying into. While it could be said that there is corruption if they are taking a higher percentage than another type of delivery service in comparison, but I find that to be subjective.
