I can't stand people like this. These women obviously didn't want to pay for their meal so they apparently tried to scam the restaurant by placing some of their own hair on the pizza, and claiming it was already there to get a free meal. Sadly it worked, and they even got a free round of drinks for their "trouble."
But then the manager got suspicious when the hair didn't match anyone's on staff, so someone checked the surveillance camera. Sure enough, the customers were caught on video doing their literal dirty work.
The customers got theirs though. The footage made the local TV news, and obviously went viral.
