Not only do you have to be 21 years old to get into a bar, but also to get into this McDonald’s in Fairfax County, Va.

The fast-food joint, located at 5600 Franconia Rd in Alexandria, recently introduced an age limit for customers looking to dine in.

Per NBC Washington , customers now have to ring a bell before entering the establishment so IDs can be checked. A sign explaining this new policy was placed on the door on Monday.

The McDonald’s is located down the street from a high school, which has seemingly caused an uptick in fights breaking out between students and workers at this location.

“Due to repeated incidents of student violence, this McDonald’s location is temporarily closed for dine-in service to anyone under 21 years of age. This decision was made to protect our staff, our guests, and our community,” the sign reads.

It continues: “Adults — we are still here to serve you! Please ring the doorbell and a team member will assist you."

The outlet spoke with a customer, Stacey, who shed light on the students’ behaviors that led to this new rule. “These kids are off the chain. They have no respect, no discipline. And it seem like how they acting, their parents are allowing them to act.”

She added that while dining at the Golden Arches location with her grandchildren, she observed older kids disrupting other diners. “Like we’re sitting down eating, y’all smoking, y’all drinking, y’all cussing,” she said. “Like, come on, y’all.”

Ultimately, she said she was OK with the ban. “I understand where they coming from, because that’s turning customers away. If you’re here, you’re acting up, they losing they business.”

Footage obtained by NBC Washington showed students getting into physical altercations with employees.

In a statement to People about the new policy, the Fairfax County McDonald’s Operator said: “We love being part of the Edison community and we value each and every customer. We’ve enhanced our Franconia Road McDonald’s security measures in an effort to create a safer environment for our staff and customers.”

The statement continued: “This policy was developed in partnership with local school officials with oversight from local law enforcement. This serves as a temporary fix as we work towards a long-term solution for all. We thank our community for its support, understanding and patience.”

McDonald’s customers under 21 are still allowed to order food from the location via the mobile app.
