POTTERVILLE, Mich. (AP) — Nearly everywhere you look inside one Michigan McDonald’s, there’s an 18-year-old Curtis.

Leith, Logan and Lucas Curtis work in the kitchen; Lauren Curtis is responsible for the front counter; and Lindsey Curtis handles the lobby and dining area.

The quintuplets all work at the same restaurant in Potterville, a town near Lansing. Their mother refers to the arrangement as “McCurtis.”

They’re not identical, so the five make it through most shifts without customers recognizing they’re siblings. But Curtises account for about half of the restaurant’s staff on a typical Sunday shift. They also make up 11 percent of their senior class at nearby Potterville High School.

Restaurant owner Renee Draves loves having the Curtises on the job. She says, “being a quintuplet, they know teamwork probably better than anyone else.”
