Washington: Sasha Obama, younger daughter of US President Barack Obama, is taking some time off from the comforts of the White House to work at a seafood joint in Massachusetts. Sasha, 15, who has lived for eight years in the luxurious confines of the White House, is learning how the other half lives this summer, the Boston Herald reported. The First Daughter took up the job at Nancy's -- a seafood joint on Martha's Vineyard at Cape Cod in Massachusetts where the Obamas like to visit for the summer vacations. Sasha, using her full name, Natasha at Nancy's, has been familiarising herself with the service industry and her duties include collecting cash, bussing tables and prepping the restaurant before it opens for lunch. “She has been working downstairs at takeout,” said a server, adding “We were wondering why there were six people helping this girl, but then we found out who it was.” Sasha was accompanied to her summer job by a contingent of six Secret Service agents, who sat outside the restaurant in a large Suburban SUV and on the takeout benches while the President's daughter served hungry tourists, the Boston Herald reported. The food joint is a favourite stop for the Obama family, who always pop in for a seafood feed when they are on their annual Martha's Vineyard vacation. The Obamas' youngest daughter has been working an early four-hour shift at the busy, 350-seat restaurant, finishing up just a half hour after it opens for business at 11.30 a.m. According to the BBC, photographs show Sasha wearing the restaurant's uniform of blue T-shirt and cap and working at a till. The Obamas have been attempting to raise their daughters as normally as possible, which may be why they are letting Sasha get a taste of working a summer job in a restaurant -- a big change from life in the nation's capital. Her last day at work is Saturday, when the rest of the Obama family arrives for vacation. Sasha and her older sister Malia, who will attend Harvard University in 2017 after taking a “gap year", attended their first-ever state dinner in March.
