___Fish McBites fail to spark McDonald's sales NEW YORK (AP) â¿¿ McDonald's new Fish McBites failed to hook enough diners to get the fast-food chain's U.S. sales growing in February. The world's biggest hamburger chain said Friday that a key sales figure was down 3.3 percent in the U.S. for the month. When excluding the extra day of sales in February of last year, which was a leap year, the company said the figure was flat. That was despite the rollout of the Fish McBites nuggets in three sizes, which were also offered as the first new Happy Meal entree in a decade. The struggle to grow at home reflects the mounting pressures on McDonald's, which had managed to pull away from its rivals and thrive during the Great Recession. ___ New TSA policy on knives, bats sparks backlash WASHINGTON (AP) â¿¿ Flight attendants, pilots, federal air marshals and even insurance companies are part of a growing backlash to the Transportation Security Administration's new policy allowing passengers to carry small knives and sports equipment like souvenir baseball bats and golf clubs onto planes. The Flight Attendants Union Coalition, representing nearly 90,000 flight attendants, said it is coordinating a nationwide legislative and public education campaign to reverse the policy announced by TSA Administrator John Pistole this week. A petition posted by the flight attendants on the White House's "We the People" website had nearly 10,400 signatures early Friday urging the administration to tell the TSA to keep knives off planes. ___ Wal-Mart executive Leslie Dach to leave in June NEW YORK (AP) â¿¿ Leslie Dach, who played an influential role in reinventing the image of Wal-Mart Stores Inc. in the face of mounting attacks by labor groups and other critics, is leaving the company in June after seven years.
