TMZ published video today of the infamous couple from Kitchen Nightmare chasing a patron out of their restaurant with what appears to be a large knife.

Amy and Samy Bouzaglo, the proprietors of Amy's Baking Company in Scottsdale, Arizona became internet-infamous after they were filmed terrorizing customers and staff members on an episode of Gordon Ramsay's Kitchen Nightmares.

Now they're back in the news with a weekend disturbance that required a police response.

According to KTAR, Amy became enraged after kicking a drunk patron out of the restaurant. Although the customer reportedly acquiesced, the situation still escalated.

Reports CBS:

Witnesses said Samy Bouzaglo, who operates Amy's Baking Company with wife Amy, was waving a knife and yelling as he chased a drunken man out of their business, according to a police report. Scottsdale police Officer David Pubins said authorities were called to the restaurant Saturday at around 5 p.m. to investigate a disturbance. By the time officers arrived, the man was gone.

The couple apparently tried to convince TMZ that the knife-like object in Samy's hand was actually a pen.

Local police told reporters that charges could be pending if and when the drunk patron is identified and interviewed.
