The woman who insisted on getting the new Blu-Ray for $5 because she found it in the $5 bin. She claimed it was the fault of the employees because they didn't make sure it was where it belonged. Everyone was chastising her for stealing.
For some reason, it brought to mind my own experience. I had gone to Wal-Mart to get some dog food and some stuff for a BBQ we were having that night. It wasn't a lot of stuff, so I put the dog food bag (big 30lb bag) in the basket; not underneath. I went through the quick check out at the garden center and I remember being surprised that the total was less than I had figured up. I just assumed my math was bad (I have a really hard time doing mental math). I got out to the car, got everything put in, and I looked at the reciept. Turns out, the cashier didn't ring up the dog food. Normally, I would have said something, but I was already out to the car. I wasn't going back in to correct them.
