The only biting allowed at restaurants is the kind that involves food.

A Canadian restaurant patron allegedly assaulted a staff member and a fellow diner on Tuesday night over an apparent mask dispute. According to witnesses, the suspect did not appear to be sober during the altercation.

The incident occurred around 7 in the evening at a restaurant in Victoria, CTV News reports. The suspect allegedly entered the restaurant without a mask and appeared to be intoxicated (witnesses said that the man appeared to have been using drugs).

A staff reportedly told the man to put on a mask, which resulted in the suspect punching the restaurant worker. According to reports, several employees and customers helped to restrain the man until authorities arrived.
