Not lovin’ it: Crime-ridden NYC McDonald’s has started carding people at the door

It was one Big Mac attack too many.

A crime-ridden Brooklyn McDonald’s is carding customers at the door and forbidding anyone under 20 to enter without a parent or proper ID — in what might be a first for the fast food goliath.

The restaurant, at Nostrand and Flatbush avenues took the drastic step last week, after a group of kids wearing ski masks swirled in after school and attacked a security guard, breaking a glass door, according to manager Amber Hussain.
