Has anybody ever gotten in one of the limos that are just hanging around the airport and ask you if you want to take a limo instead of a taxi. They say that they got a few hours to kill until their next job, so this is a way to make a few extra dollars on the side.

I am fully aware that they are not supposed to do this, and in fact, it is illegal. Nevertheless, has anybody here done it, and if so - any problems?
