Every national chain store, including car dealerships, McDonald's, Lowe's, Sears and yes, even Walmart are only as good as the people working there - period. Finding good, qualified people who are willing to work for the wages offered can be a difficult and demanding task.
Slight divergence here! I can remember the "golden years" of the auto industry well - the 60's. Auto companies were looking for warm bodies and nothing else. No education required, just the ability to follow orders and do menial, repetitive tasks. While I love cars from that era, the quality was horrible and this hiring practice was a major portion of that policy. Today, though hiring practices everywhere have changed, it's difficult to find good, conscientious people with good people skills who are willing to work for $10 or $12 an hour because those wages won't raise a family. That is what's wrong with moving from a manufacturing economy to a service based economy. I strongly suspect in GSN's case, it was an employee who may have been polite but was too lazy to take the item to the proper area to be removed from the sales floor.
