Can you imagine being charged almost $10,000 for a 1-mile cab ride? Margarita Bekker, 51, had a cab take her from the Powell Street subway station in San Francisco to a restaurant where she celebrated her husband’s birthday. The fare was only $7.90, but she says she was charged $7,900 plus a 25% tip, totaling $9,875. She says the cab driver claimed to have made a mistake and promised to refund the money, but that didn’t happen. She also ran into problems disputing the charge with her bank.
