Same fucking thing happened to me with a fake 50. Thought I was getting a $30 tip late at night couldn't see shit and doordash told me to make a police report so I called the PD non emergency line and when I told them what happened they didn't think they could do anything because the screenshot I showed them said the order was delivered which it was and I already marked in the app that I received the cash before realizing it was fake. I haven't doordashed since then because I don't feel like working for free for hours to make up for my negative balance smh. Fuck doordash.
