So I bring my Wii filled with private information expecting it to be wiped of all its content before being sold again. A few weeks later there are these nutballs giggling like schoolgirls laughing at the names of my families mii's! On youtube! I was extremely annoyed by this. You would expect better service from such a popular chain. Needless to say that day was the grumpiest moment of life.
