Police arrested a 35-year-old man Saturday at a South Lake Union restaurant after he attacked wait staff and tried to dodge his tab.

The man tried to pay for $227 worth of Scotch whiskey and fish and chips at World Sports Grille about 5:30 p.m., but his credit card was repeatedly declined, according to police reports.

From there, things went downhill.

The man offered to leave his laptop computer and car keys as collateral, but staff declined the proposition and asked that he pay up.

He then said that, as a member of the “Sicilian mafia,” he would come back and “whack” everyone. [Ed. note: subtle, bro.] The man also claimed he was a member of the CIA. [Which is it?]

Eventually, he made a run for the restaurant exit, where he took a swing at a staff member who tried to block him from leaving. The employee dodged the blow.

Restaurant staffers chased the man down the street until they detained him and called police, reports say.

Responding police found the man lying on the ground. An employee reported his shirt had suffered a “significant amount a spit” from the mouth of the suspect.

Mid-arrest, the man told staff “this isn’t over” [I’m sure] and pledged to return to the restaurant.

Police booked him into King County Jail for investigation of theft, assault and harassment.
