Okay, I've been searching online and haven't found the answer yet.
Why do Combined taxis charge an extra $2 when paying by EFTPOS???
Obviously I don't take taxis regularly, but a recent hauling of stuff from parking lot 400 meters away from my apartment has taken its toll and I decided to spend $7 for convenience.
The taxi driver warned me about the charge but I had no cash with me at the time, and I rarely do because this is NZ -- one of the EFTPOS lands I know of.
