Piece of finger served to diner after worker accidentally cuts self at restaurant

BLOOMINGTON, Ind. (AP) — A diner found a piece of human flesh on his hamburger shortly after a restaurant worker accidentally cut his finger, and a spokeswoman said the company was “very, very sorry.”

A kitchen manager at the TGI Friday’s at College Mall injured himself Tuesday and no one immediately realized he had lost part of his finger while others rushed to help him, said Amy Freshwater, a spokeswoman for the chain.

Another staff member served the plate to a customer, who immediately spotted the piece of flesh.

Gross, yes, but I ask you: how much different from beef flanks could human fingertips possibly be?
