How do I know someone else hasn't already done that? It's entirely possible someone did exactly that, shoe was the wrong size or they simply didn't like it, and back on the shelf they went.
PS I hope you never buy a new car. You'll never sleep again.

In my experience they do the same at the apple store (open the phone that is) unless asked to do otherwise.
You guys are being completely ridiculous now. Bad example I made about the shoes. And the car comment. My partner's parents made sure there were no km's on the new car they purchased. They specifically asked for one that didn't have any...yes..some people do that, it is their preference!!!! Deal with it.
