Rachel McAdams is one of Hollywood's most coveted actresses, but one fast food chain probably isn't clamoring to have her back.

"[I worked at McDonald's] for a good three years," the 33-year-old star tells Glamour magazine. " I was not a great employee; I broke the orange juice machine one day." 

Despite her lackluster job performance, McAdams describes McDonald's as "a great place to work."

"I had a little bit of an OCD thing with hand washing and just didn't have time," she explains to Glamour. "They were like, 'Hey, the drive-through's backing up. Stop washing your hands!'"

So why did McAdams find herself flipping burgers under those famous golden arches? "I was 16 and directing kids' theater, which didn't totally pay the bills," she laughs.

If her acting career hadn't panned out, McAdams "wouldn't mind running a restaurant."

"I'm not an amazing cook," she admits. "But I can follow a recipe!"
