I was taking a cab from Union Square to Brooklyn a Saturday night at 4 a.m. Once in Brooklyn and $30 later, the driver informed me that his credit card machine wasn’t working. I didn’t have any cash. He threatened to drive me back to Manhattan because I only had a card. He then locked me in the cab, cursing and yelling at me. I couldn’t unlock the door and the driver was so angry, I started crying. Eventually I had to call 911 where I had to describe the driver which was awkward. “He’s black and bald.” At that point, he finally unlocked the doors and I got out and he drove away angrily.
