I've always walked into CC and have felt like the store managers just didn't give a damn and instilled exactly that same feeling in the employees.
Often you walk into departments in complete and total disarray. You can't find what you want, half of the displays didn't work, DVD and CD sections are impossible to find what you are looking for in, etc. The sad part was then seeing 3 or 4 sales guys just standing around instead of fixing the stuff so that it was in pristine condition.
On the other hand, a year or two ago I was in Cleveland and walked into a brand new CC and it was very impressive. Perhaps because it was new, but it felt more like a BB, and had a cohesive setup that let me find what I wanted as well as having people that were well enough trained to answer some questions. I ended up buying, and letting them install, a car stereo for me. I wasn't thrilled with the way it was installed, so the guy happily offerred me a couple of different options on changing it, and made the change that I said I wanted - without an additional charge to me. So, he didn't do it wrong, he just picked one of the possibilities, and then happily made it exactly what I wanted.
It would be a shame for BB to lose that competition in the market. But, there's no doubt that when I go into a CC it always seems dingy with people that don't care working there instead of a well kept store like I feel when I'm in BB.
