POTTERVILLE, Mich.  — 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 of the restaurant where the quintuplets work in Potterville. Their mother calls the arrangement “McCurtis.”

It started about a year ago when boss Renee Draves asked Lucas Curtis a question she often poses to her younger workers: Did he and his co-worker/sister have any siblings looking for a job? She was floored by Lucas’ answer.

“She wondered if we had any other siblings, and, funny enough, we did,” Lucas said, smiling.

Lucas is the youngest of the quintuplets, born three minutes after older brother Leith. Lucas and his sister Lauren started working at the McDonald’s last fall, and their three siblings followed suit earlier this year.
