An Uber Eats driver went on social media and shared something that customers do to a lot of drivers. He said it's something called "tip baiting". This is when a customer offers a large tip to get their food faster and then take it away in the end when their food arrives.
He said that Uber Eats has a function where you can add another time or decrease your original tip. The driver said it's a function that's often abused by customers.
