On Thursday, September 28, 2017, at 8:00a.m. I was trying to hail a taxi at the corner of Delaware and Mies van der Rohe. A green Taxi Town cab #3114 pulled up and I approached the driver side window which was down, to see if he was available for a passenger. He started yelling at me (I couldn't understand what he was saying or why he was yelling at me for that matter). I took out my phone and took a picture of cab number, when he started advancing on me, super angry, yelling "I told you I am going to the bathroom". I support my Chicago cabbies everyday to and from work. Guys like this make me want to start using Uber.
