A male customer at a Dairy Queen restaurant in Canada was so enraged by the eatery's stance on face masks that he allegedly urinated over the counter in protest.

As reported by CTV News, the man, whose identity is not yet known, was caught on camera appearing to relieve himself in full view of staff at Dairy Queen in Port Alberni, British Columbia.

Footage of the incident was captured by a customer standing behind the man.

In the video, the man can be heard arguing with employees at the establishment and refuses to put on a face mask - until the tension eventually escalates to a point where he unzips his pants and apparently urinates over the counter.

Staff members are then heard reacting to the bizarre stunt in utter shock.

According to the Royal Canadian Mounted Police, the incident occurred at about 9 PM on Saturday, August 28.

"Staff there got into a heated discussion with him and he was asked to leave. He became verbally aggressive and abusive. He left the restaurant only to return shortly there after, and urinated at the counter," RCMP said.

"This is the first incident of this nature," said RCMP Sgt. Chris Manseau, per the outlet. "I think people should just wear their masks and be safe and be polite."

The publication reports that officers are yet to make an arrest and are asking anyone with footage of the encounter to share it with the authorities.

Needless to say, the footage has sparked outrage online, with many branding the man an "anti-masker".

One person took to the comments to write: "And they wonder why the anti maskers are view as infantile whining babies - this one needs a diaper."

Another wrote: "It’s such a weird vibe. There are people clinging to the exterior of airplanes to escape the Taliban and this guy is butt-hurt because someone wants him to wear a mask to protect other people."

While a third added: "Absolutely disgusting, hope they throw him in jail at least for the night and would imagine they shut down DQ to do a proper cleaning and sanitize (ugh nasty)."

A final person wrote: "They don’t get paid enough. What kind of disgusting human would do that! Just put on a damn mask!"
