Can anyone explain to me why anyone would ever shoplift at Walmart?

I am not saying that I have never boosted from Walmart, I mean I did it once when I was 12 years old right after I started smoking weed and it was fun and exciting, but the way they have the cameras set up, and how they watch you like hawks and stop you before you even get in the door, and the fact that you are pretty much guaranteed to get caught if you try to walk out with anything, makes it seem like a really stupid idea.
