Costco also fires employees for their moral convictions. In Canada a guy lost his job when his Knights of Columbus hall wouldn't rent out to another Costco employee for her gay "wedding reception."
I was just checking the threads while my wife is out at Walmart. She had to return to the store since the Electric razor/trimmer we bought to cut our sons hair was already used.
Imagine opening a new product, or so you think and seeing someone elses hair come tumbling out. I told her to just return it as I'll pay the extra $2 for a clean product from Target.
Not that it will affect their overall success but that can turn you off to the whole chain.
