There is this additional cost of 5% for credit card processing, which I do not understand why the city says the driver should not pass on to the customer.
I do not understand why the cost should not be passed on to the company leasing the cab.

I do belive the company is paying less than 2-1/2% but rips off the driver at 5%. I know one company that charges 7% to credit cards.

I think it is only fair to let the customer have a choice of paying cash or 5% more for credit card use.
