While she made a wise decision to not drive, she made an unwise one for calling a friend who had no license.
So the problem lies with this:
Driver is not licensed.
Passenger must drive, which can not happen because they have been drinking, so this is a no go.
So vehicle is parked and a tow is called.
Passenger now is forced on the side of the road to wait for another ride, they are now in violation of being PI'd.
The answer to this story is to not call a friend who has no driver license, and this does not happen .
Or have enough money to stay in a hotel for a night. I'll transport if the person is cool, and is willing to stay.
