As I mentioned before, during our vacation to Atlanta in 2017 we took the Amtrak train. As soon as we arrived at the Atlanta station, it is a bit chaotic with all the people going to their destinations. But I do remember seeing lots of taxi drivers. They were waiting like parasites, coming up to everyone and asking if they wanted a ride or not.
I already had it all planned out. I managed to dodge them, but I would have said "No thanks, I got Uber!" to them.
