Naz Ali, who had never eaten pig meat due to his religious beliefs, was dining with his family and friends at Farmer John’s in Sutton Coldfield.
Speaking with the Birmingham Mail, the 39-year-old truck driver admits he never asked staff what kind of meat was used in the dish and assumed it was chicken.
Mr Ali, who ordered a beef burger along with the side of fries, said he ate about a quarter of the dish before checking with the waitress.
He says when he complained staff apologised and gave the children in his party free desserts.
But the pub’s management claim they also waived the entire bill after Mr Ali complained, reports The Birmingham Mail.
Mr Ali said: “My friend said I should check what I was eating [after you’d eaten “a quarter” of it. Quick thinking there – Ed.] so I asked the waitress and at first she had no idea.
“Then she came back and said she was really, really sorry because it was pork.
