What happens if you choose Joja Mart?

I know I could just look it up, but I'd rather hear it from the players rather than a "players guide" on Wikipedia. So, what happens when you decide to choose Joja Mart instead of fixing up the Community Center? I've always chosen to fix the center because I hate corporate greed in general, so saving the small town community store and the center always made sense to me.

You guys can even tell me what you did in your games as a result of choosing Joja, or just completely fabricate what actually happens. Whichever one is good for me. You'd just have to have some kind of disclaimer for misinformation at the end of your comment or something.

I wasn't sure if this is just common knowledge, but thanks in advance!
