Blame it on low blood sugar.

A Staten Island fast food customer flew into a fit of rage — flipping off employees and smashing a glass window — because her Popeyes combo meal didn’t come with a soft drink, police and other reports said Friday.

The woman, who ordered a $4 Wicked Good Deal meal, is shown in security footage throwing a cardboard sign before breaking the window with a chair inside the restaurant on Forest and Veltman avenues Sunday, according to police.

The hungry hothead flipped out when workers explained that the order includes chicken strips, one side and a buttermilk biscuit — but no
beverage, a Popeye’s worker told NBC New York.

She was drunk and likely mistook the deal for a Wendy’s $4 meal, which includes a soda, the employee told the station.

Cops are hunting for the woman, who is between 18 and 25 years old and was wearing a pink bandanna and hoodie.
