I guess it depends on the location. I had a car service pull this on my at Denver International a few years ago. He wasn't asking for more than the flat-fee from downtown to the airport, so I hit the ATM and gave him the cash. But if I had been in a hurry, he would have been SOL, I would have gone straight to security and not given it a second thought.
