I've never had a face tattoo myself, but from what I hear they were one of the more painful places to get inked. If she was actually asleep she had to be on drugs or something. I mean try falling asleep when someone is stabbing your face with a pin hundreds of times per minute.
That's the big issue if the girl really was asleep or not. The man who worked on her face claimed she was awake and he did not give her dope/drugs. But yeah honestly how can you sleep with pins attacking you every second. Simply rubbish.
