A Brooklyn deli employee was punched by an irate customer who tried to stab him and opened fire inside the store over the weekend, cops said Thursday. 

The suspect walked into Aden Deli and Grill on Rockaway Parkway near Smiths Lane in Canarsie minutes before 10 a.m. Saturday and argued with the 41-year-old worker over wait times for food, cops said. 

The customer then punched the worker and tried to stab him with a knife before leaving the store, police said. 

A short time later, he returned with a gun and fired two rounds into the store, cops said. No one was struck. 

The worker refused medical attention at the scene, police said. 

The suspect then took off in a black Mercedes Benz SUV, heading north on East 96th Street, cops said. 

Police released surveillance video and photos of the suspect early Thursday. 

The bald man, with a dark complexion, is believed to be between 50 and 60 years old. 

He is shown wearing a white T-shirt with the words, “G-Star Originals,” as well as blue jeans and brown shoes. 

The incident comes as similar violent acts have recently erupted in and near delis, bodegas, smoke shops and other small businesses in the Big Apple.
