I just came off an airplane today. I sat next to a woman who told me her friend had paid an Uber driver $140 for a ride. He had come up to her at the airport and asked if she needed a ride.
You NEVER pay an Uber driver. The money part is paid by to the driver by the company. Tips are included in the price you pay. Your payment is to the company.
Uber drivers NEVER ask you if you need a ride. You call the company and they send a driver.
And, by the way, if you call for an Uber driver in Chicago, you'd better have your coat on. They come so fast it is unbelievable. The company contacts a driver close to you, and they are there fast.
