It's a sign of the economy:  Walmart is cutting greeter positions from it's 3rd shift.

The move will save money and ensure Wal-Mart has the right staffing levels during peak and non-peak hours, David Tovar, a spokesman, said in a telephone interview. For the past six months, Wal-Mart has been reassigning greeters at the company’s approximately 3,000 U.S. supercenters from the third shift, which runs from 10 p.m. to 7 a.m., to other jobs, he said.

The ends a 30-year tradition of making sure that Walmart customers get a full-service experience.
