Best Buy orientation

I had my orientation with Best Buy yesterday, and it was...interesting. It was extremely high energy. When they opened the doors to the (very large) convention room, all of the supervisors were lined up on both sides of us and all of them gave us high fives and hugs. Very weird. They had some "pump up" music playing, like the Venga Boys and stuff. They played that music all day. Throughout the day, they made us do these cheers. If we weren't loud enough, we had to do it again. Stuff like "BEST BUY" and "PROTECT THIS HOUSE" and some stuff in Hawaiian. Again, very weird.

Of course, they made us watch a bunch of videos on how great Best Buy was and we had to listen to each manager give a speech on what their department is and why it's important. They also had us do some creative activities like make a styrafoam ball into a head and explain what it means to our group. Since I'm on the geek squad and we are all geeks, ours naturally looked like a geek and had no other meaning than that. Then we had to come up with a departmental cheer. None of us were really into it other than the two supervisors.
They put a lot of effort into this "culture day," but there was something very fake about it all. I am not getting good vibes from most of the supervisors. I could tell that the GM (general manager) was genuine and seems to be a really nice guy, and one of my supervisors seems like he'll be cool. As for the others, I have a feeling they might turn out to be jerks.
I did actually enjoy interacting with people. I guess it's obvious that I'm not from Hawaii, because just about everyone asked me where I'm from. I was one of the few "howlies" in the group. Just about all of the rest of them were from southern California. It's kind of cool to be in someplace so culturally diverse.

I'm really not convinced yet that this is for me, though. I think I actually prefer working in a cube farm (office). The store doesn't open until Nov 18, which means that we'll be doing training and helping to get the store set up until then. My sisters come out on the 23rd, and I would like to spend time with them rather than work. Plus, they've already told us that there's no way we'll be able to get the Friday after Thanksgiving off, which is the day that we're going to the UH-Badger game. I really want to go to that. I'm torn - I know that if I'm not going to stick this out, I should just let them know now so they don't waste their money on me, but at the same time, it seems like easy money - not really work, just training. I think that I am going to quit before my sisters come out, since I'd be quitting before Matt got home, anyway. What would you do?
