From the NY Times article about the Wal-Mart pullout in Germany:

In Germany, Wal-Mart stopped requiring sales clerks to smile at customers — a practice that some male shoppers interpreted as flirting — and scrapped the morning Wal-Mart chant by staff members.

“People found these things strange; Germans just don’t behave that way,” said Hans-Martin Poschmann, the secretary of the Verdi union….

Ah, surly German clerks. Brings back fond memories. Some description of the Wal-Mart chant can be found in this article. Americans are probably the only people on earth who can do it convincingly.
