Customer gives me a downvote and takes away the tip because I asked for the orders pin number?

This is the kind of bs Uber allows to happen to us. These are the kind of things that need to be reversed how can you get your tip taken away and a downvote for literally asking for the PIN number for the order. Then customer states she doesn't like meeting delivery drivers well too bad you have a PIN number because you probably did something shady before and said you didn't receive your order or something along those lines. I should have known better when I started getting these texts I should have just canceled.
