Pirahna Bar owner Mathieu Malouin posted the shocking video to Facebook in praise of the calm demeanour of bartender and assistant manager Valérie Gaudreau. The video shows an individual brandishing a baseball bat and proceeding to cause damages to the bar, the video lottery machines, and even the bar's glass doors.\nThe unnamed vandal is known to Piranha Bar's staff and patrons for allegedly harassing them after he was first kicked out of the bar for disturbing customers in December.\nThe assailant's frustrations apparently came to a head when he came to the bar armed with intent to cause chaos.\nAs Gaudreau calmly dialled the police, a small group of shocked patrons looked on as the man smashed beer taps and a couple of machines.\nMalouin tells MTL Blog that the man would "try to get into Piranha Bar since we first kicked him out and make death threats to me and the doorman. He came back every night and our security guard would make him leave."\nThe video (seen below) shows the individual, who wore all black and has his face covered with a ski mask, approach Gaudreau with the bat.\nPosted by Mathieu Malouin on Monday, January 6, 2020\nAfter she seemingly ignores him, he proceeds to smash the beer taps, nearly hitting the bartender's hands as she was pouring a beer.\nAlerted by the noise, the bar's patrons cautiously move away from the man and one customer even flees the bar and runs outside.\nThe man then walks over to a row of VLT machines and smashes them with the bat. As he proceeds to leave, he drops something, picks it up, turns around, and destroys another beer tap.\nPosted by Mathieu Malouin on Monday, January 6, 2020\nAs seen from another angle, the man smashes one of the bar's glass entrance doors before he runs out of the establishment.

Stay calm and call the police," says Malouin.\nBon ils ont enlèvé cette vidéo ! Pourtant c est une situation réelle . Aussi c est un exemple de sang froid et réaction...Posted by Mathieu Malouin on Monday, January 6, 2020\nThe incident is a reminder that Montreal bartenders have to deal with all kinds of wild and dangerous situations on a day to day basis.\nThe service industry is one of the most unforgiving and if it takes a steely demeanour like Gaudreau's to set a good example for other industry professionals, I'm all for it.\nSo next time you find yourself at Piranha Bar, leave Gaudreau a big tip and stay for a metal show.
