I had a terrible experience with Yellow Cab when I needed to travel from Miami Int. Airport to the Coast Guard base on MacArthur Causeway, a 15 minute ride. We agreed on a $32 flat fee. The driver insisted he knew how to get there and I gave him written Mapquest directions but he got lost and it took almost an hour. Then he insisted he didn't have change for a $50 bill. I assume he wanted the difference as a tip. Never again will I take a Yellow Cab in Miami.
