A video of a crazy security guard shouting at people in a coffeeshop has gone viral. The man was picking a fight with people and in a fit of anger, wanted to flip the table beside him. The woman who was eating at that table has earned the praise of the internet as she fought back by trying to throw a chair and a cup of water at him. Thankfully, the police arrived after a good few minutes. It is unclear why he was so angry but as a security guard, the last thing to do is to jeopardise other people's safety.
