Ahh, that reminds me of the time my friends and I were at Walmart to buy her Guitar Hero 2 game and a controller and an iPod for myself. We found the game within the first five minutes of walking around in the store, but it was behind the glass, of course. So we looked around and NOBODY was in the electronics department.
We waited for the cell phone booth lady to finish up with a customer (which took 20 minutes), and then asked for her to get someone to help us. She called someone up to the electronics dept, and that took another 10 minutes before the lady who worked there actually showed up.
When she did, we got the game and the controller, and when I asked for the ipod, she made me wait for another 15 minutes before she finally told me that there weren't any more.
In other words, Walmart sucks.
