Return Policy?

Well, it was another exciting day of studying. After I got done with that at about 11:30pm, I decided to go to the store to buy groceries.

As I was checking out, I was behind these three (apparently) high school guys, who were trying to return some car stereo part, while obviously high. It was also obvious (to me, anyway) that what really happened was that the guy bought one of whatever it was before, broke it, and then decided to go buy another one, switch the broken one for the new one in the packaging, and return the broken one. It's not rocket science. Of course, the cashier went right along with it, because, what's she gonna do, right?

At least, that's what I thought was going on.
