Consider this conversation I had with an employee at Best Buy

Of course, that's an example of every conversation with every employee at Best Buy. I actually like the store, but I do my best to avoid eye contact with the employees, so I don't have to hear "can I help you?" 500 times a visit. I wouldn't mind if they knew something, but they don't, so I don't want them speaking to me

I also have yet to see a Karma in the stores. The only thing I've seen for it was that Maxim (Stuff) article. But I can understand if advertising isn't needed.
