Last weekend, my parents came in from Houston to visit me. Aside from re-arranging the furniture and going shoe shopping (the usual parental visit stuff, I guess), we went to a few very nice dinners. Unfortunately, I made a reservation for a place across town just as the Cubs game was letting out, which meant that every cab in a five-mile radius was filled with a drunk Cub or Cardinal fan. Even Uber, my usual go-to for getting a cab, was saying there wasn’t a cab in most of Chicago. So, inside the Uber app, I flipped the slider from Uber to UberX. Suddenly, a Toyota Camry was only three minutes away and was ready to take us to dinner.
