Why were the Grecian widows in Acts being neglected?

Les explains that after 606 B.C., when Nebuchadnezzar took Israel captive to Babylon, only a few thousand returned to Jerusalem to reestablish temple worship and prepare the nation for Christ's first advent. The rest assimilated throughout the Gentile part of the Roman Empire, taking those nations' language and customs while keeping their Judaistic practices. When such Jews came to Jerusalem, they were called Grecians—Jews who had been a generation or two outside Palestine. Thus the Grecian widows were non-Palestinian Jewish widows, and they were being cheated, pushed aside as outsiders, and neglected in the daily ministration. That daily ministration was the daily dole of food and clothing, whatever they needed. The twelve, with Peter as headman, then called the multitude of disciples and said it was not reason to leave the Word of God and serve tables. Les notes the Bible does not call these men deacons, though they played much the same role.
