I must admit, I used to go in to the Bose store near my college and screw with the employees. Not in a mean spirited way, or to make them look stupid, but for a different purpose each time.
The first time, I was just curious to see what they would say. The next couple times I wanted to see if it was consistent across employees. Once I even spoke to the manager of the store. I was always polite and courteous, but asked tough questions that I got from "google."
I also was helping to educate a friend of mine about audio and I took him to the Bose store, after taking him to a fairly decent audio store, to compare. Obviously a Bose employee came up to him to make the sales pitch, but I had prepared him with questions to ask and to ask if he could play a demo CD he had brought with him to the other store.
The Bose employee checked with the manager and they declined, they provided unsatisfactory answers where the other store's employees provided helpful and insightful answers, and a guy who previously thought Bose was top notch audio now had the veil lifted.
Bose has it's purposes, just none of them involve spending money
