A Milwaukee food service worker with a carry permit had enough after another waitress was attacked by an irate customer.

In the above video from Wisconsin ABC affiliates, a man is seen going behind the counter of the George Webb restaurant on June 29 before he viciously punches a female manager/waitress. In response, a second waitress draws a handgun from under her apron and points it at the man, who eventually retreats.

"It is sickening to see this unsuspecting worker assaulted so brutally by this individual," said Milwaukee Alderman Bob Donovan in a press release urging the public to contact police with information on the suspect.
