Wal-Mart pulls out of Germany. Their business model simply doesn't fit into the German retail landscape. One of the main reasons:
The company initially installed American managers, who made some well-intentioned cultural gaffes, like offering to bag groceries for customers (Germans prefer to bag their own groceries) or instructing clerks to smile (Germans, used to brusque service, were put off). (Source: NYT)
Never, ever smile at a German. Know thy customer!
Next time Wal-Mart enters the German market, they should search for employees more adapted to the wishes of the local customer.
