It was a big avoca-don’t.

A Bronx deli just a block from Yankee Stadium failed to keep its employees safe, claims a worker whose jaw was broken by an irate avocado-hurling customer.

Amr Al-Zabidi was on duty at the Stadium Deli on May 29 when two customers, angry their food order was messed up, went berserk.

Surveillance video caught the rampage of Brad Gomez, 28, and another man, who became irate when they tried to talk to Al-Zabidi, who doesn’t speak English. Gomez then gathered up a handful of the heavy fruit and slung it at Al-Zabidi, breaking his jaw. The two men were charged with assault.

The store’s negligence and lack of security led to the attack, Al-Zabidi claims in a lawsuit.
