London: Hollywood actress Rachel Mcadams says she started her career with a job at McDonald's.

The 'Sherlock Holmes' star said she spent three years flipping burgers at the fast food chain along with two of her siblings, she reported.

However, the 33-year-old insists she wasn't a good employee as she was too obsessed with cleanliness.

"I worked there for a good three years. My sister and brother worked there. My sister was my manager. It was a great place to work, but I had a little bit of an OCD (obsessive compulsive disorder) thing with hand washing and just didn't have time.

They were like, 'Hey, the drive-through's backing up. Stop washing your hands!' I was not agreat employee; I broke the orange juice machine one day," Mcadams said.
