I find that BB's customer service levels have much to do with how well the employees know and/or like a type of product. Our local BB is a larger one and there is no trouble getting help with computers, TVs, game systems, cell phones or car stereos. However, book reader devices, appliances, small house stereos, or old computer games are very hit and miss. There is currently one guy whose wife wanted a book reader device so he learned about them for her and is great at offering assistance now, but if he is not working you are pretty much out of luck. So I think it very much has to do with the employees not wanting to feel or look stupid because they don't know anything about a product and since it doesn't have any relevance to their personal life it is not worth the off-the-clock time to learn and the company isn't going to pay for the time.
I have had pretty good luck going to the greeter person and saying that I need help with a specific item or department and would he/she please find somebody to assist me since nobody on the floor volunteered. I do limit those questions to things that can be looked up in the inventory system and don't require actual product knowledge though. Since the greeter is also loss prevention as previously posted, he/she tends to be more than just a flunky level employee so he/she can call for a flunky and best of all cis stuck at that desk which rarely has a line to wait in to get a question answered. And there are always lots of witnesses around to see if the requested customer service is provided.
