"Which one is the man, and which one is the woman?" That is a question I have faced more times that I can count. Taxicab drivers generally pose the question while they are hauling me around Manhattan. The exchange goes something like this.
When you swipe your card, the driver has to pay a hefty 5% extra. Why are New York's cabbies paying so much? Because of all the middlemen. A few people are making truckloads of money on drivers' backs.
When taxi drivers find themselves alone in their cabs -- as they often do -- with psychopaths, scam artists, or even just garden-variety drunken idiots, that little hands-free device can be a lifeline.
