I first heard of this from a client when I told him I would be taking a cab to his hotel late at night. I had been out on an extended dinner date and wasn't driving as I had been drinking, so the safe choice would be to take a taxi, right? But according to the police, a woman traveling alone and under the influence should never take taxis!
The sad part is that I am not surprised by this. I have been harassed numerous times by cab drivers. Once last winter I left the bar after many drinks and the driver suggested I ride in front where it was warmer. Because I was drunk, I complied without thinking. Upon arrival at home the driver pinned me down and kissed me. I managed to push him away and get inside safely.
Ladies be careful if you are using taxis, stay safe out there.
