Not sure about a decrease, but you can easily get it fully refunded if they fuck up. I tip really well because I used to be a food courier myself. Every few months some idiot delivers my pizza upside down or leaves my order outside my building and I get my tip refunded with ease. I have no idea if that money is refunded from the dasher’s pay though.
Can you decrease it afterwards?
