On Saturday Apr 12 at approx 9:00 a.m. I was in the back of Yellow cab # 56. It was a $15.00 fare. Upon arrival to my destination, I pull out my Visa card to pay. The cab driver first tells me that he does not accept credit cards. I say sir, there's stickers on your window that says you do. So then he says well the machine is broken. I say well sir, how come you don't tell customers that when they first get in the cab? So, he tells me to "go find an atm". I say sir, this is a C.C., not a debit card and I am trying to pay you. He begins to get VERY irrate and says im wasting his time and that he "has all day" to wait. I need to go with him to a gas station and buy him $15.00 in gas then. I say sir, Im late for work, and Im trying to pay you, but you say you dont take cards. I called yellow cab during this time, and Yellow's management said he should not be out taking fares and for him to call yellow. He says I don't have to call F***ing yellow, I'm independent, and I want my money. I go to open the back doors to the cab to get out, and they are Jimmied shut so that you can not open them from the inside when they are locked. I am essentially TRAPPED in the back of the cab. The cab driver LAUGHS at my attempts to open the doors to the cab and says if I find a way out, he's calling the police. So, there I am, trapped in the back of a Yellow Cab. Finally, after 30 minutes, I submit to it and have him take me to the gas station and I was forced to buy $15.00 worth of gas and WALK back to my job, some 1/2 mile away. Angry, Embarrassed (3 of my co-workers witnessed me in the back of the cab, one came to the window and tried to open the door for me, but since it was locked, couldn't.) I was held, against my will, in the back of Cab 56, on Sat Apr 12 at roughly 9:00 a.m. to 9:30 a.m. I will be filing a police report on this incident and would appreciate some legal feedback. Thank you.
