The 35-year-old actress currently serves as shop assistant and spends her spare time working with her spouse Peter Sarsgaard in a co-operative supermarket near their home, reported Contactmusic.
"We work at this place, it's a co-op and if you work there you get cheap groceries. I don't do it because you get cheap groceries, I do it because they have incredible food and incredible produce. You cannot just pay to be a member, you have to work there," she said.
She prefers to be less conspicuous while working.
"I've worked in the office but I have a new shift now, down in the basement where you put the apricots in the little bags. You get in trouble really easy there. They have a lot of rules and I've missed shifts, but I try. I try. I've worked in the office before and people call up and lie!," she said.
