But, would he have been properly ("adequately") trained for the job of assembling bikes? I think there's a common idea out there that "that kid at Wal-Mart with a wrench is going to mess up putting your bike together," but I wonder how much veracity this concern has. Of course, an experience mechanic at a bike shop will (should) know "more" than a person at a big-box store, but, the question is, will the latter have adequate knowledge to assemble a bicycle properly? If not, there's a problem; if so, there isn't one.
