McDonald’s, the world’s largest restaurant chain, said sales at stores open at least 13 months fell 1.8% in October, the first monthly decline in nine years, as US customer traffic decreased.

McDonald’s, the world’s largest restaurant chain by sales, said third-quarter profit fell 3.5% as sales growth slowed at US stores.

McDonald’s, the world’s largest restaurant chain, reported a 4.8% gain in first- quarter profit as new menu items such as Chicken McBites attracted US consumers.
