I've had a cab driver from JFK to Manhattan try to add tolls to the ride. When we went over the Manhattan bridge a message appeared saying a $14 toll was added. Had to argue with him and he kept saying "No sir, there are tolls when you come into Manhattan, all of the tunnels and bridges". I had to literally stress to him I drive in the city and know you're trying to scam me. He took it off but I still filed the 311 - called in and he plead guilty to it. It's worth following up about.
