I work at Wal-Mart and believe me, the people they put in electronics are complete morons.
We have had so many things stolen from our electronics area it is ridiculous.
For instance: The day Halo Wars came out every copy we had was stolen before it could be put on the shelf.
The jackass in electronics left the box full of brand new video games/movies (all that were needing to be refilled or were just coming out that day) in a shopping cart by electronics while he/she went to the restroom and someone managed to walk out the door with that box without being stopped by the door greeter (which BTW is a 70 year old lady that is legally blind and from my experiences around her more than likely has severe Alzheimer's).
Yay for ignorance.....oh wait, STUPIDITY!

.
The only reason I care is because we get a bonus (usually around $200-300) if the store makes it above sales and events like these cause us to get less if any at all.
Anyways back on topic, I saw a RROD on the 360 at FRY's when the power shut off and came back on from a thunder storm.
