A “dirty, long, filthy fingernail” was almost swallowed by a disgusted diner at Watford Jimmy’s World Grill in a mouthful of made-to-order Indian pancake.
Antoinette Miller, 42, from Cassiobury, was eating a specially prepared dosa pancake when she felt something crunch in her mouth.
The church volunteer was “disgusted and appalled” and left retching into her food at the table when she pulled out the offending fingernail.
Managers at Jimmy’s, in High Street, apologised for Ms Miller’s experience but said the nail had come from another guest helping herself to the buffet.
Ansh, manager at the Watford Jimmy’s, said the incident had been investigated and none of his staff were responsible.
He said the most likely explanation is that the nail came from another customer.
He said: “The lady was very upset, we did not give her the bill and explained to her what might have happened – that the nail came off another guest helping herself to the food.
“I would be outraged if it happened to me. We apologised, paid for the meal and invited her back for another meal.”
