Michael Morgan, 20, is charged with attempted murder and criminal possession of a weapon.
Camellia Dunlap, 18, is charged with two counts of criminal possession of a weapon, a loaded firearm.
Police say Dunlap handed a 9mm handgun to Morgan who then opened fire.
The incident unfolded around 7 p.m. Monday inside a McDonald's restaurant in Bedford-Stuyvesant.
Cold French fries led to gunfire at McDonald's, officials say
Officials say Morgan's mother was at the restaurant and complained to the victim, a 23-year-old man who was working behind the counter, that her French fries were cold.
The argument escalated, and the woman called Morgan, who police say went to the restaurant to confront the worker and ended up shooting him outside.
He remains in extremely critical condition at Brookdale University Hospital.
Morgan has 13 prior arrests.
The shooting is the latest in a number of recent incidents of violence against fast food restaurant workers.
In May, a McDonald's worker was stabbed multiple times defending other employees from an unruly customer in East Harlem.
And in January, 19-year-old Kristal Bayron-Nieves was fatally shot during an armed robbery inside a Burger King in East Harlem.
