There have been some unusual disturbances over the years but there cannot have been many more bizarre than the Brooklyn hot dog riot which broke out at a New York restaurant this month.
Customers at The Shawarma King deli spotted a non-kosher frankfurter wrapper, then spotted a cook barbecuing the sausages on the grill.
In the ensuing disturbance the cook was surrounded by angry customers.
He flourished an electric knife to fend off the crowd.
