Bill Wisth, who stands at 6-foot-6 and weighs 350 pounds, said he went to the all-you-can-eat fish fry Friday at Chuck's Place in Thiensville and was angered when the restaurant cut him off after he downed a dozen pieces of fish, WTMJ-TV, Milwaukee, reported Tuesday.
"It's false advertising," Wisth said.
Wisth, who called police while arguing with workers, said he was not satisfied when the restaurant gave him eight more pieces of fish when he left.
"I think that people have to stand up for consumers," Wisth said.
Wisth returned to the restaurant two days later with a picket sign and said he will stand outside the eatery every Sunday until it changes its policy during the all-you-can-eat fish fry.
Elizabeth Roeming, a waitress at the Chuck's Place, said Wisth was cut off because the kitchen was running out of fish. She said Wisth has caused disturbances at the restaurant before despite making allowances for the customer, including allowing him to run up a tab that he has yet to pay.
