SALT LAKE CITY -- A couple on a low-carb diet were kicked out of a buffet restaurant after the manager said they'd eaten too much roast beef.

Sui Amaama, who along with his wife have been on the Atkins Diet for two weeks, was asked to leave after he went up to the buffet at the Chuck-A-Rama in suburban Taylorsville for his 12th slice of roast beef.

"We've never claimed to be an all-you-can-eat establishment," said Jack Johanson, the restaurant chain's district manager. "Our understanding is a buffet is just a style of eating."

Offended, the couple asked for a refund. The manager refused and called police when they would not leave.

The couple said they have eaten at Chuck-A-Rama's $8.99 buffet at least twice a week, but did not plan to return.
