What confuses me most is when you are given the option to give a tip before any service has been given. On deliveroo, for example, I have the option to tip the driver while I'm at the checkout. Why would I give a reward for good service when I have no idea if the service is even good? There's already a rider fee as part of my bill, so it doesn't make any sense to me to give them more money at that point
